Union Update: GU4 and Twitch Drop Event

With July 30 less than a week away, the release of our first big Season Pass DLC „Sunken Treasures“ and our Game Update 4, which includes many quality of life changes, draws ever closer. But before we share the full release notes of GU4 with all of you, we want to talk about our upcoming “Sunken Treasures” Twitch Drop Event!

During the Event, which starts this Friday July 26, you will be able to watch how a variety of select Twitch Streamers explore Cape Trelawney and dive deep to retrieve lost treasures. But getting a preview of the upcoming content is not enough, as watchers of the streams will be able to unlock two exclusive billboard ornaments for their Anno 1800 game.

The only thing you need to do is to watch one of the selected channels playing Anno 1800 for a set amount of time while having your Uplay account linked to your Twitch account. And if you haven’t done so yet, you can check on how to link your accounts here: Ubisoft Twitch Drop FaQ

If you entertain yourself with Anno 1800 during the event for one hour, you will get the „Anarchy“ Billboard ornament and if you binge a channel for three hours, you will obtain the „Sunken Treasures“ Billboard to beautify your city.

Game Update 4 Release Notes

Game Update 4 adds support for Anno 1800’s first DLC pack, “Sunken Treasures”, for all Season Pass owners. In addition to buying “Sunken Treasures” as part of the Season Pass, you can also buy it standalone or as part of the Anno 1800 Gold Edition (which includes Anno 1800 Digital Deluxe Edition and the Season Pass).

While “Sunken Treasures” is paid content, everything you will find in the Release Notes below will be free for all Anno 1800 players as part of Game Update 4.

You can now zoom the camera significantly further out, giving you a better overview of your majestic islands (which you can activate in the Gameplay options menu).

We have further improved and optimized game performance, leading to smoother gameplay across most graphics settings. As part of this, users will now also note an improved viewing range.

A new, improved minimum stock system has been added to the Trading Post. In order to replace the old system, we need to remove the old settings from all your existing trade routes.

We have reworked and rebalanced Expedition rewards to make them feel more rewarding across all difficulty levels. New expedition reward tiers per difficulty are now:

Easy => only uncommon or rare rewards.

Medium => Only rare or epic rewards.

Hard => Only epic or legendary rewards.

We have improved the usability of the trade routes menu, adding a text filter and a toggle for other ships displayed in the trade route menu strategy map. You can also select these ships to add them to your trade routes from the strategy map. Hovering over a trade route entry will now immediately show the trade route on the map. Finally, trade routes are now sorted alphabetically to make them easier to keep track of.

We have reduced the notifications spam for low threat incidents. Incidents such as small fires which are no major threat will no longer trigger a notification.

After several bargaining rounds, we have convinced the workers responsible for loading and unloading oil onto your trains to work faster, resulting in these operations happening twice as fast.

Incoming trade ships will now make full use of all harbors on an island, trying to avoid lengthy traffic jams in front of one harbor while others remain unused.

Architectural expos in your world fair will now reward you with more than three ornaments at a time.

Previously defeated pirates will now bring a small fleet instead of a single ship upon their return to the game. It now takes them 30 minutes to rebuild.

The multiplayer chat has been completely reworked.


Rebalanced the quality of rewards granted by resident quests.

Generally improved the generation of rewards for a variety of activities (quests, drops etc.). This can lead to some items appearing less often, while some previously very rare items will appear more frequently.

Rebalanced the moral value for difficulty level three expeditions. The morale bar should now fill up faster.


  • Fixed an issue with missing objectives for “Open Book 2” voluntary quest provided by George Smith.
  • Fixed a missing icon in quest tracker/book for Princess Qing’s voluntary quest “Shadow Puppets: Part 3”.
  • Fixed the “jump to location” button for Princess Qing’s voluntary quest “Shadow Puppets: Part 3”.
  • Fixed the “Hostage Rescue” campaign quest where buyable frigates would fight Pyrphorian ships.


  • Fixed the specialist items “Actor” and “Sarah Bartok” which previously had an invalid effect for the Theatre building.
  • Fixed the “Poster of the Leader” item not having any effects (it now provides additional workforce and a bit extra happiness, but reduces taxes).
  • The “Footman” specialist item now provides more taxes.
  • Fixed items increasing the maximum residents being inactive after loading a save file. The item effects are now also calculated slightly different than before. Affected items are “The Withdrawal Amendment”, “Contraception Regulation”, “Papal Paper of Prenatal Preservation”, “Jakob Sokow, The Charitable Banker”, “Louis P. Hecate, Arm-Puncturing Pioneer”, “Chief George Doughty, Smouldering Hero”, “Saint D’ Artois, Vision of the Valley”.


  • Fixed an issue where a player could not be re-invited to a saved multiplayer match if they were not on the Uplay friend list of the player loading the save file.
  • Fixed the cancel invitation button having no icon in the “Invited Friend” section of the multiplayer lobby.
  • Added an error message for the client if the host leaves the multiplayer lobby.


  • Fixed an issue with the electricity icon being shown in the World Fair’s Foundation menu before electricity is needed.
  • Fixed text input in the trade route menu being reset if the player didn’t press the ENTER key.
  • Fixed “session transfer” or “expedition assigned” text overlapping the cargo slots in ship menus.
  • Fixed truncated text in ship menus when transferring to another region.
  • Fixed debug text being shown in trade menu tooltips if the camera was moved to another island in the background.
  • Fixed an UI issue in the charter route setup that occurred when dragging the amount slider out of the box, which could accidentally close the goods selection window.
  • Steam ships and sailing ships now have different icons to make them more distinguishable in the trade route menu.
  • The edit screen of the newspaper now shows the currently available influence (previously the publish button would just be greyed out when the cost exceeded the available influence).
  • Fixed an issue with overlapping icons in the marketplace menu when only artisans, engineers and investors were present on an island.
  • Fixed the working conditions menu sometimes not remembering values if the player would change the productivity by typing in the text field instead of using the slider.
  • Fixed the construction menu not remembering the category sorting when loading a save file.


  • Fixed an issue with flickering dirt roads while zooming the camera.
  • Fixed firework effect persisting after loading a save file


  • Fixed a typo in the German localization of “Die Amazonen” expedition screens.
  • Fixed a German localization issue with Margaret Hunt’s reaction to one of their buildings being destroyed.
  • Fixed a typo in the English localization of the “Iron Dragon” expedition event.
  • Fixed English text shown in the German localization of the ship object menu if the player would send a ship to another session.


  • Oil ships should now approach the correct coast when multiple oil ships are assigned to a trade route.
  • Improved visualization of ships traveling between sessions on the world map.
  • Fixed ships moving at their individual fastest speed even if the “grouped” option was selected.
  • Fixed an issue with defeated pirate ships still being shown on the mini map.
  • Improved display of highlighted buildings when using the demolish tool.
  • Added three new filters for notifications when ships set on a trade route encounter a problem.
  • Fixed buffs granted by animals in the Zoo staying active even after the main building of the Zoo was demolished.
  • Fixed an issue in the newspaper after a war declaration where the player’s name was shown instead of the name of the AI declaring war.
  • Fixed several misleading tooltips in the World Fair menu.
  • Fixed visitor pathfinding around the Bank building.
  • Fixed the “Load Game” entry in the main menu being visible without a save file being present.
  • Fixed an issue where the last playable game profile could not be deleted without restarting the game.

    Thanks for the DLC, but I need Statistics Building

    So I just got my second billboard, but I think the wording is off in the drops info panel:

    It is one hour get Anarchy Billboard
    Should be : Watch 3 <> hours to get Sunken Billboard.

    And I suspect you have to watch 4 hours on the same guy, because until I did that last evening I didn’t get the second one.

    Have fun with the DLC guys.

    So I’ve been having this problem since May 6, well before that really I contacted Ubisupport on the 6th (Case Reference # 08828802) On May 12th a Daniel C from @Ubisoft Support told me that the problem was known and to “Keep an eye on our forums and the Anno Union ( ) for all future updates and patchnotes.” Well its been about 3 months, 4 updates and the 1st major dlc is now dropping. So I really hope that this problem is actually being looked at cause I would really like my flagship back. The crew didn’t pack enough rations for 3 months of real life.

    I just saw in my game the two ornaments 😀
    But I didn’t get any message or somethings else.
    I can find them in Uplay.
    But I did find them in my game.

    Best regards,

    @Katje-Katrien – you have to be logged into twitch and under the title of the stream, under the video it needs to say drops enabled in green text.

    in other news :D, I am over 6 hours still only got the first billboard :P. (6 hours combined from 3-4 streamers in which 3 hours from vallegaming and I can’t speak German even to save my life so imagine my effort ),

    Literally none of those streamers…

    ValleGaming (German) monstersandexplosions (German) writing_bull (German) Baso (German) AnniTheDuck (German) Caaaaate (English) HeyChrissa (English) Mathia (Dutch) Midnan (Dutch) Achterklap (Dutch) Koinsky (French) Scok (French) EasterGamersTV (Turkish) Chiches (Spanish) rockalone (Polish) losiugra (Polish) urqueeen (Polish)

    … are streaming Anno right now. I totally would have streamed for every hour I was online (I play Anno too much, lol).

    How would I sign up / volunteer for it next time?


  9. BlueBreath BlueBreath

    @I actually have over 5 1/2 hours but I only got the first billboard today in the morning.
    Let’s hope it is ok I don’t really watch streamers on daily bases.

    Also guess what was the most common word in the chat :P.

    how about adding an upgrade mechanic for only power plants? adding a smaller plant to extand the range for electricity ? i dont want to fill my island with power plants and downtown railroads… i mean seriously. investor residances around railroads because they need electricity? an upgradable mechanic like oil harbours or anno 2205 like one should be awesome for power plants.
    and nope. trade unions or town halls are not an option for it. dont even consider it.

    When I click on the link for Ubisoft Twitch Drop FaQ, I see a list of all participating Streamers that is bigger than the one that is mentioned here on the Anno Union site.

    Do we have to watch 3 hours in one time or can we watch 3 times 1 hour to have the “Treasures Billboard Ornament”?

    Can I watch a German Streamer? And how do I know when he starts streaming?

    Can you please elaborate further regarding this specific line:
    “The item effects are now also calculated slightly different than before.”

    What exactly changed in the calculation – thank you.
