Update
11/18
Improvements to the spawn system to resolve an issue where negative spawn influencers from specific game events were not always being deleted after the danger had cleared in some matches, this was causing good spawns to be erroneously flagged by the game as bad spawns, which in turn forced actual bad spawns to get selected later in the match
Experimental slight reduction in knife lunge range this is a trial change
Prevention of Prestige glitching trying to prestige from Combat Training will reset your stats but not give you prestige (AKA PATCH 50.14.32.3)

Jobo50 wrote To everyone - This prestige glitch was LIVE PATCHED. BUT if you haven't reset your XBOX 360 recently and are still on playlist patch 50.13.30.3 you're ay-okay with this and can prestige at will (if you find someone else to do it with)
