Despite having only two composters, I am once again left with three Farmers in my village. I have a hunch that since one of them has been traded with, somehow it forgot about its own work station and another villager claimed that station, despite the fact that 1.16 was supposed to add a feature where the Farmer that was already traded with would have claimed that work station again. This is one of the most frustrating bugs that has persisted through three versions of the game so far.
