So I was, just for fun, trying out a dual challenge, going for AoMC and AoD. I noticed that even on Phobos entry, the formers were respawning. Are they supposed to do that? I was on Hey, Not to rough, there were obviously no Arch-Viles nearby, but mobs sprang out of the ground regardless.
Is there some undocumented thing to Angel of Darkness that makes mobs respawn?
