last time i checked and figured it out where was the problem and its on attacker side.
On game, when i start playing as an operator while on attacker side, game suddenly crashes with no reason, no error, it just crashes.
but in defender side its all fine untill it goes to killcam (which is still on attacker side) and then crashes.
make it fix already, many ppl on this community and bunch of my friends have the same problem
atleast pretend that you care for your customers!
