Put the summary of the bug you're having here
What I expected to happen was...:
Farmer villagers to harvest/replant crops or to pick up food I dropped for them
What actually happened was...:
Villagers are not picking up crops, not harvesting crops. I checked using /track villager breeding and villager inventory states 0 (zero)
Steps to Reproduce:
1. Observing Farmer villagers not harvesting fully grown crops
2. Dropped stacks of bread, carrots, potatoes, beetroot for the villagers to pick up but they didn't
3. Opened command /track villager breeding to check villager inventory status and it is set to zero, indicating villager inventory empty.
Please check what the "mobGriefing" gamerule is set to. If it is "false", villagers won't be able to pick up items.
