Ravanger spawned inside a house during a raid

I was doing a raid at a village, and came across various bugs. To start with, I noticed that when completing the raid and getting the hero of the village reward, the raid bar started climbing back up and started another raid after the finished one. I also noticed that the hero of the village effect only lasts 30 minutes after a raid and doesn’t come back in that same village. Anyway, I also noticed that this ranvanger spawned inside a house, which did make it easier to fight but probably isn’t an intended feature.
