Still having an issue with the Librarian villagers. I leveled up 2 villagers to master level, their initial trade is bookshelves. I also leveled up about 4 to Journeyman. Logged off yesterday evening, 10/15/24. I logged in this morning, 10/15/24, and one of the Bookshelf Librarians was back to Apprentice along with a few of the others that I had leveled up to Journeymen. It seems that this occurs when I log off the game and later log back on. All other villagers are working fine with keeping their highest trade level.
