[Vulkan] Invisible Enemies in Lair Map

Hi, some of the enemies in Lair map are invisible for me on the Vulkan renderer, I did not test with DX11 renderer since it's in the map and I killed them.

I believe they were plumed chimerals, they looked like they did the feathery barrage tail attack. Their attacks were visible, but the character models were completely invisible (e.g. 0 visual indication a pack of monsters was there). All the packs I encountered like this were normal. As soon as the took any damage, they appeared on my screen like normal.

They were invisible throughout the entire map, not just one pack which loaded in slowly which is a different issue I think.
