I noticed earlier a lot of games I was getting Loaner - "most kills with enemy weapons" but didn't remember ever picking up an enemy weapon.  I just played a match and got it again, but also got Hot Potato "Most grenades thrown back".  I know for a fact I didn't switch weapons once and didn't throw back a single grenade.  Unfortunately I have theatre switched off so can't review or prove it, but I am 100% certain.  So, for me the stats in this game are broken. 

Anyone else noticed anythng strange on this?
