Impossible for Villagers to Breed with MobGriefing False

Put the summary of the bug you're having here

What I expected to happen was...:
To have the villagers be able to breed and pick food (carrots) up, continuing to create kids.

What actually happened was...:
When given carrots/having farmers,  they don't pick up the food or farm, therefore not creating kids when the MobGriefing was turned to false.

Steps to Reproduce:
1. Put villagers in a close area ready to produce
2. Give Carrots to them
