I set up a farmer with hoppers and cobweb to collect bread thrown to another villager.
No crops were in sight to harvest.
Gave a stack of 24 wheat to start bread making. Let it run. Two double chests filled up with bread.
Another bug possibly related. When shutting down game and reloading, farmers were holding the bread and would not do any other actions (harvest/plant)
This is game breaking for villages...
