To the developers, try this. I was able to replicate this in a realm where theres also 2 players having villager trading hall close together (500x500 block radius) and this realm also have lots of redtone farms. What I do was that, first i tried to link beds on one villager then after that i will allow them to link to my desire working station for them (in this situation, the lectern) the repeatedly break them so i can get my desired trade for them. After some time, i manage to get my desired trade to at least 5 villagers. But in the 6th one, the villager dont want to link to their working station. When i tried to break their beds and work station then put them back again, they dont want to link to it again. So i think if you tryto do this you will see/replicate the bug.
