illager patrols spawning even when the village inhabitance is all dead.
how to reproduce:
- find a village (my one was a custom village)
- kill all villagers in a village with /kill @e[type=villager]
- wait for a patrol
(this screenshot is from 1.14.2 as you can see by the vindicators, but it has happened on 1.14.3 pre 1 and 2 as well)
