The in-game stats page shows me as not having any stars for weapons (except the ones carried over from vanilla BC2) even though I earned the bronze star for the M40 in the last match I played. The details show 0 kills for the weapon. 
 
Also, it says my best vehicle is the Tuk Tuk with 0 kills when I've definitely gotten some kills in the tank. 
 
I'm guessing the servers are just completely stressed (haven't been able to update bfbcs.com since the 18th) but I want to make sure I'm not the only one.

Hmm, updated now. 
 
At least the servers seem stable.
