My brother and I have a multiplayer survival world that we've had since 1.14 came out, and suddenly after using 1.14.3, we cant trade with our armorers anymore! It seems to be world specific, as we can go into our own singleplayer worlds and we can trade with armorers. What happens is we go up to either of our 2 armorers, the menu pops up for a single frame, and then closes. We tried trying to trade with them while only one of us was on the world with the world closed to LAN, and it still didn't work.

EDIT: we went into creative and spawned a new villager which turned into an armorer, and we could trade with that one. still unable to trade with the other two, however.

EDIT (again): a new villager spawned into our village and he appears to have taken over one of the armorer's blast furnaces. One of the 2 un-tradable armorers doesn't work at his blast furnace anymore and the new villager became an armorer we can trade with.

EDIT (again, again): One of the untradeable villagers is tradeable with now! However, the new tradeable one is now untradeable with
