While creating a villager trading hall, multiple villagers linked to one smithing table, grindstone, and blast furnace at once. Unsure if intended or not as a feature but can cause issues for villager halls on servers and singleplayer worlds.

Yes, multiple would link to one station and they'd be stuck in that profession, I tested more on my test world, those seem to be the only blocks that link with multiple villagers and the villagers don't lose the profession.

Did you break and replace their working station?
