I have a cartographer linked to a cartography table. And I have a librarian, where when I break the lecturn it becomes a cartographer and the previous cartographer loses their profession. Basically, a villager that is 100+ blocks away is linking to a table that another villager is already linked to. This did not affect 1.17.4, but only 1.18. This bug has been present in previous Minecraft versions but returned somewhere between 1.18 and 1.18.2
