Minions dont leave their current task to accept new tasks
For example. If a minion is using a workable tile he will often refuse to leave that tile even when the task is already done. The most obvious example i have is minions not leaving the barracks to get paid and then complaining about not being paid. I experienced this example in the new undergames expansion.
Another example is cultists continuing to research even when the maximum sins have been reached instead of automatically leaving the podium and either wandering or moving to the barracks. I experienced this bug in the second mission of the main campaign but i suspect its tied to my first example and part of a larger problem.
As far as i can tell nothing has prevented minions from going to the tavern as i havent gotten any hunger alerts.
