A lot of enemies spawning in walls and ceilings lately

[Sepharoth]

The last couple of days, I have had a lot of enemies that have spawned inside a wall or the ceiling. I know this can happen at times and I have had it happen before to me but it was very few and very far between. But the last couple of days, there has been way more than I have ever seen before. Not sure what the issue is and why so many have started to spawn in the walls and ceilings now but I just wanted to give you a heads up about it. Maybe this is a more common occurrence than I have experienced before and I just happen to be the one seeing it now.

Yep, I noticed that as well. Enemies spawn in walls or above me, and then I spend a few seconds looking around to see where's that goddamn enemy I see on the minimap. It's a really common occurrence lately, which is rather strange, cause it didn't use to happen at all for most of my playtime (almost 3000 hours spread across slightly over 4 years). They also sometimes spawn in the floor, but ceiling and wall spawn is a lot more common.
