    Hi, found some bugs
    1. Defectors quests are missed after update, when you playing with Hugo Mercier.
    2. Changed AI of pirates, now they are no longer chasing your transports
    3. And what about new flamethrower monitors, they are still unusefull, coz no shooting.

    I had several relogs into anno 1800, cause time going makes game slow. After last login i stopped playing, ’cause i don’t wanna ruin +200h of playing. The game adds to the real amount of needed workers the needed workers without items-usage.
    I downed the workforce to 0 on every production-island, except some mines and power stations. – i have oder 25000 ingeneers needed per island. I already deleted ministrys and and set items newly. – The game adds the workforce without any multiplier to the real amount. – No Mods ever. – PLEASE FIX! It’s weekend and I can’t start even a new playthrough, cause this **** f***** me up the 4th-6th relog.

    Witam niestety aktualizacja nie naprawiła u mnie przeciwników AI nadal nie ulepszają budynków zatrzymują się na rzemieślnikach i dalej się nie rozwijają. Grę dwa razy odinstalowałem i instalowałem jak i dwa różne scenariusze zaczynałem za każdym razem to samo. Pozdrawiam

    Hello, unfortunately the update did not fix my AI opponents, they still do not improve buildings, they stop at craftsmen and they do not develop further. I uninstalled and installed the game twice, and I started the same two different scenarios each time. Regards

    Hi Devs,

    since this new update, there is something wrong with influence point in all of my saved games: I have around -1000 in all of them. Other players are probably affected as well. Could you, please look into this matter?

    Thanks a lot in advance!

      Hi guys,

      I face exactly to the same isue as ThomasTom88 – despite I have built previously only few Flame Towers (which should be the only one affected by increase of influence costs), I am now almost – 300 on influence points. And I can not see why… At this moment the game is almost not playable.

      Thank you a lot for your urgent help!

    Вы издеваетесь? Вы можете пофиксить квест с Башней? Когда я привожу узников к Арчибальду он не может их взять. Я перезагружал ссесию, перезагружался и прочее и он ИХ НЕ берет. Что за треш. Или у Вас не хватает рук это починить??

    “Be- und Entladegeschwindigkeit für Post wurde stark erhöht. Sie hat jetzt eine eigene Ladegeschwindigkeit im Vergleich zu normalen Waren”

    Das ist toll, aber was bringt mir das wenn die Luftschiffe mit normaler Fracht fast immer zum Lufthangar fliegen und sich alle dort ansammeln und aufs Entladen warten. Ich dachte, es würde vielleicht zusätzlich eine Priorisierung für Luftschiffe mit normaler Ware für Anlegestellen/Kontore kommen.

    I don’t see the news reports being mentioned. The most unbalanced goods in the game. There’s no way the need of the entire population of scholars will ever be satisfied for reports. Really annoying

      The thirst for knowledge can never be quenched! 😉

      Obviously, it depends on your scholar population size 🙂
