New villagers are suppose to pick up carrots. Farmer villagers are suppose to farm.

All existing villagers and new spawned villagers in that world now stop farming and stop picking up any crop even if I go far away to new land.

I have had trouble reproducing this bug. I used mc edit to copy blocks and entities to a working world but it stayed working. But I think it happened while messing around with villages and doors. Even after breaking the villages and doors, new villagers will never pick up crops and farmer villagers wont farm.
