I'm not sure if it qualifies as a glitch, but it sure didn't happen in AO. But
if you jump in a wall in AE and fall a long way (a screen or two) down on your
back, you don't end up dead when you hit the floor. It might have been
because I was using the invincibility cheat at the time when I discovered
it in the Slig Barracks levels.
