I think I found out the source of the crashes...
I was playing this a couple days ago when the game updated and all the crashes happend.. And, like lots of other people, have crashed almost everytime they've entered a server.. I entered a few servers and crashed on everyone. except one that didnt connect to the item server..
Then the next day (which is today) I play again.. I start crashing again everytime I play on a server.. Then I read the discussions about the game crashing and found someone posted about them not crashing when loadout is down.. So, I tested it out.. I unplugged my Internet and played on offline practice.. I didn't have my loadout.. and, strangely enough, no crashes..
So, I'm just gonna guess that the Item server is making everyone crash... What do you guys think?
