Thanks Ayuri, red rlist does the trick for viewing a rooms resets. My problem with instaroom still stands though, which is that there doesn't seem to be a way to set the maximums for each reset. So the two guards that I've got resetting in one room will reset just fine, but every time the area reset comes around, it adds 2 more, rather than checking to see how many there are and replacing any that may be missing/deceased. When I use instaroom, it essentially seems to be multiplying the number of instances of a given mob by 2 and using that as the limit/maximum for the reset.
Are you supposed to purge after adding your resets, perhaps?
