Ok, so let me clarify, apparently I never got this fixed (and just noticed).
I can create a mob in a room, instar the room.
I check redit rlist and the reset is there.
If I reset area, another one spawns. (even if the other one is still there, and this only happens once, otherwise it stops at 2)
And then, if I purge the room and reset it again nothing will happen. And it still shows they're SUPPOSED to reset.
