So we were just doing veteran Banished Cells for the hundredth time; killed all the keepers, killed the big scary daedroth, killed the harvester sisters, killed Rilis ... And then this happened:

Basically, the daedroths and Rilis's healing orbs didn't stop spawning even after he was dead. Although we had some fun with the daedroths and the orbs floating around aimlessly for a while, this is the second time it's happened to us. Wondering if anyone else has seen it?
