A few months back, I was playing on the last level solo, I then decided to do the banchee glitch to get a banshee inside Tartarus' Lair. While in there the battle was going normally. I killed him a few times the quickly reverted. The he jumps in front of the banshee and I push him down below. I'd done this before, so I waited, and waited, but he didn't come back up. I looked to where he fell and he was nowhere in sight! I waited some more and the game didn't end, I thinking he was dead. So I go to get some milk and cookies while little arbiter sits by sgt. johnson. When I get back still no Tartarus, so I end the game. This all occured in the timespan of an hour. Can anyone justify this mystery, any shedding of light? Thx
