Can confirm this also happened to me, I went back and checked the log file, and it's full of "exception loading entity: q: loading entity NBT" as others have pointed out. since this is an entity loading error, do the villagers still exist in the save and can't be loaded, or are they permanently thanos-dusted? I have cheats on in my world for this sort of eventuality, so I'm not in too much of a pickle if I have to train them all up again. However, if they still exist in the save and can be restored in a future snapshot, that would save me some work.

 MC-74762 makes note of the full disk null-pointer-error that caused my issue. Seems I was barking up the wrong tree when I was looking at MC-315. Thanks, I think this should be marked as a duplicate of that issue

This still happens in 1.14.4; I have a small village with 3 composters, a brewing stand, and a stone-cutter, but after some mining, I came back to find that I had an extra farmer and an extra mason. The original farmer and mason, who where the only villagers I had leveled up, had been disconnected from their blocks (the jobless villages "stole" them) so the could not refresh their trades. neither of the other farmers, nor the priest, none of whom had been leveled at all, had their workstations stolen. it would seem that only villages who have been leveled up are susceptible to having their workstation stolen.

A related issue: on 1.14.4, I have two villagers in a village, one is unemployed. there are several job-site blocks, but the unemployed villager will not take any job.
