there are three things that are wrong with my villagers.
once I have traded with my farmer villager he will eventually stop working at his composter and another villager will come and get a job at the same composter but the first one will not lose his job or levels.
once I have traded with one of my villagers even if I break there job block they will not lose there job ever.
villagers that don't have jobs will not seek out job blocks. very frustrating.
just for me, also whoever reads this please don't kill wandering traders. I like them and there trades. (Mojang pleas fix this bug it's driving me bonkers.)
now my villagers are disappearing. :c
