I was in the N millitary base and killing zombies with my hunting knife it ruined after a few and i went to pull up quickslot and it would freeze me, (wouldnt pull up any slots for my guns) and id still be getting hit. The only way to stop it would be to press start and exit and try to run if im not already surrounded... I have a video i could send its happend a few times but its been okay cause i know to press start but i cant do that forever
