Have a librarian villager that won't reset his trade of an emerald for paper. I've traded his other trades to raise him a level, and been back to the village many times but it doesn't reset. He has a lectern, and that is what is supposed to reset when he uses it according to the wiki.
This is a strange village, has 7 beds but only 3 villagers, and I can't seem to get them to breed any way.
Never seen him at the lecturn. He wanders around all day but I've never seen him enter the building, just standing on steps. If I make another lecturn, should I place it in the same building or somewhere else?
There is no bed in library, so he must sleep elsewhere. I'll try putting one in building he might use to sleep in.
Some of my villages work as expected and some have the problem you describe. Certain villagers don’t find their workstations or beds at night even though there are plenty of unused ones. Try breaking the lectern and placing it again when your librarian gets close to the building. I’ve started to place workstations in front of houses to make it easier for the villagers to find them and easier for me to see when they are being used. If your villager doesn’t go near the workstation you can push him into a boat and row him to his workstation.
