Ok..It may just be me... but my computer just updated steam when I went to run my map.. not only is the menu brighter than I've ever seen it before, the levels are all flushed.. I have the gamma entity set to 2.0 in my map but when I go to the menu and come back it says the gamma is set at 1.000005... I loaded up ns_veil just to check and it is the same thing...
to add to the bright thing - I am getting an error that says something about user message client 67 or some crap...the level loads then it just goes back to the menu... it's crazy...
