Once again my retrevier skill assessments have been resetted back to ZERO. This is the third time. Crytek, when are you going to fix this? If you are ever going to.
my retriever wont even starts up
started at 0 and still at zero.
you need about 6 patches to fix everything thats broke
Do you even play in Ranged servers?

I think you mean "Ranked" servers with a "K".
As far as retriever goes, just make sure you play for hours and hours and hours, and leave a session mid-game. Works for me. My retriever is maxed out now.
