I cured several zombie villagers and some came back with professions already assigned with no visible job blocks nearby, this creates an issue with the job blocks not registering when placed near them. Villagers that were cured and didn't have a job refuse to pick up jobs as well despite job blocks being present. Beds were not used to see if it resolves the issue, but this should be unrelated as it only affects restocking, iron golems, and villager breeding. Currently in a realm, I assume it's the latest version as it was created a month or two ago.

Steps to recreate:

1. Cure zombie villagers
2. Attempt to place job blocks nearby and notice no change taking place
