Sometimes get elevated vertically when falling
I was playing a game last night and sometime when I jumped down to the center in dweller2 map11 I got elevated vertically when falling. I can't always recreate this. Sometimes happens sometimes not. Take a look. I attached a txt file with timestamps in the demo to see specific times. TIMESTAMPS ARE FOR THE 2ND GAME VS DEVILUTION.
Unfortunately the demo is no longer available to download however there was a bit of IRC discussion that postulated the cause could be due to the server treating spectators as solid entities. This bug has since been fixed, but some experimentation showed that a live player could jump on top of a spectator and appear to be standing in mid-air.
I believe this bug is long gone.
