When playing online I was in the camp with the friends list open. My friend joined me and all the sudden a crash report popped up on the screen. I filled it out thinking the game had just crashed, but it was running fine in the background. 

HOWEVER when I went back to the game I had a whole new character and ALL OF MY INVENTORY WAS GONE. As well as all of the progress I had made (player level and missions completed) this current session (roughly 3 hours)

So now I am stuck back at the beginning of the game, because my equipment was replaced by level 1 equipment so I can't go back to the later levels and just grind for better stuff again, AND because the smith and trader are based off of POWER not LEVEL I can't even buy new equipment to go back to where I was. I have to start the whole game over again.
