On my minecraft server which I have with friends I have been trying to get the best stuff possible and make the server better while my friends are away, I created a villager trading hall inside a basic underground villager breeder.  as I started adding villagers to workstations to trade with the extra villagers started taking or 'sharing' workstations with another villager.  so much to the fact that one of the villagers in their dedicated place won't refresh his trades,  I have seen a reddit post addressing this issue but that reddit post was made when 1.14 was the newest version so I have no idea if this is intentional or a bug that has somehow became 'un-fixed'. The server does use several plugins and datapacks, and that might be causing the issue.
