How did these kind of problems make it past QA? If I do not manually leave a game by myself my progress is not saved. Thats not all though, it seems randomly the game decides to not save some progress or ignore entire matches altogether. Ive done the HMG 100 kills challenge THREE times because of this crap.

I play a game.. challenge complete 100 HMG kills.
Next pre-game lobby. 97/100 HMG kills.
Again.. I complete 100 HMG kills.
Next pre-game lobby 97/100 HMG kills.
etc.

Sort this **** out. Ive even gone down ranks and lost thousands of EXP.

It could be lots of numerous things. Such as:
A) Your playstation is having a hard time registering the fact you achieved it. (Potential corrupted file maybe?)
B) The server hasn't recognized you achieved it. (Considering the game just came out I can see how this would affect it.)
C) Your playstation may have connection problems on data retrieval. (Server to Client based stuff)
D) Your having temporary problems with loading all the achieved items and unlocks. (Much like what happens in BattleField Bad Company 2. I've had that occur on that game loads of times but all of it usually ends up coming back over time.)

I know these don't help you solve your problem but I was just giving an outlook on what the problem could be. Hope this helps in one way or another.

If you are going to assume what platform im playing on at least dont choose the minority. I play on PC.

lmfao

rofl. And yeah, it svcks. Couldn't have been tested before release. These bugs are too prevalent to make it passed a proper testing phase.
