Pillager Captain spawns

Pillager captains keep spawning in our well lit, walled in back yard. It is not a random spawn, but a regular spawn since the update and I had never even seen a Pillager captain prior to the update. I now annoyingly need to keep running for milk to remove the Bad Omen, because  the bucket of milk (on another bug ticket) will not move from my inventory to a large chest but empties instead.
