Well, I'd be suprised if anyone still checks this page, but I've uploaded a new version of TyrQuake with a fix for a fairly obscure crash - thanks to Morfans for describing a way to reproduce it on func_msgboard:

"There is indeed a bug in e2m2 whereby if you shoot one button and then
 bunnyhop across the gap the trigger inside the door will hang quake
 if you are on easy skill..."

I may end up being around for a little more Quake stuff now, but the next few weeks will tell. Life is unpredictable.
