Villagers are broken, there are many problems with villagers in 1.16.101 that makes it impossible to do any thing with villagers. Here are a list of problems that I've encountered,

1- Villagers don't pick up food of any kind

2- Villagers cant breed because of problem number 1 

3- When villagers sleep at night they tend to not stay in their bed the float away (visual) 

4-  Villagers sometimes don't unlink from their work stations when you break them 

5- Farmer villagers wont harvest their crops

6- Sometimes villagers wont refresh their trades

I would really appreciate  it if you fixed these problems =)
