I have a similar issue but it did not involve breaking job blocks. I updated the game, spent a few day cycles building, then tried to trade with a villager while it ran to a bed to sleep. I didn't break the job block so it either had trouble reaching the block or trying to trade at night caused a similar bug. edit: breaking and replacing the blocks fixed it. I couldn't get it to happen again at night so that part was probably coincidence. I also had jobless villagers stealing ownership of the block from the original ones and had to put out more job blocks for them.
