- A stupid bug where bots re-trigger jumppads if they fell onto it. - A small "memset" bug concerning player animations. - Reward sounds were never cleared and thus they are played on a map restart. - Safer and more secure handling of disconnected clients and clients with malformed or illegal info strings. - first_gauntlet_hit.wav was not played (ops/ps) bug - capturelimit not hit (from OAX)
