I don't know why, but my librarians don't recognize their workstations. I play on 1.19 vanilla, but I have a lot of datapacks installed. And I would understand if it was because one of those datapacks, but it only affects a single set of villagers - I have three trading halls, and only one of those is affected, despide being nearly identical to a working one.

So, the bug itself: when I place lecterns, the villagers seem to connect with them (judging by the green particles). However, I have a datapack that shows assigned villager workstations, and when I run the function, it tells me that they still don't have any assigned workstations, except a single one out of 15!

Could anyone please explain the situation to me? I've built an entire library just to house these villagers in the basement, and if they won't restock, the library as a whole would end up pointless...

(Edit) Not sure what happened, but relogging into the world seems to have fixed everything.
