Talk:Color correction (entity)
Annoying bug.
In CS:S, color correction appears to get "linked" to the first player to connect to the server. Once this player disconnects, everyone loses color correction until another player connects to the server. It then gets "linked" to this player but it restores it for everyone.
Yes I agree this bug is annoying and happens for HL2DM to.
Try reactivating it again by logic_timer.
