I looked up online what quests you should get on this website: https://anno1800.fandom.com/wiki/Campaign
I NEVER got "The Apple Falls Not Far From the Tree" or ANY other clear abandoned building quests.
Clicking on those only says "Not enough people to clear it". I am currently at 650+ farmers because I can't upgrade the houses.
I DID GET "Toast to the Future (Aarhant)" and finished it. Also "A Spark Rekindled" and "Loyalty Repaid"!
Also the quest with the fire but that was immediately finished because I already had a fire brigade at that time.
That's it. No more quests in the quest log.
Is the only solution to restart the campaign??
