This doesn't seem to be getting much attention... I came here looking for other reports of the problem and this is the only post I can find. I guess I will just me too and then say this.... I got the 1000 kills achievement but now my 2000 says 97 kills riiiiight. My tactician achievement also reset to 0 which is great since that one is so hard to get to register combos for in the first place. My Melee one says 2 which was never high to begin with but definitely higher than that.
For me this on PC.
Update: added screen shot, I got the Tactician achievement on steam but not Origin/In game. Yet it shows 20/20 lol.
