While Battlefield 3 players are enjoying the recent "Back to Karkand" expansion pack, DICE is working on a weapon fix. The QBU-88 sniper rifle and MG36-LMG aren't acting as intended on "Karkand" maps, since a glitch blocks the player's view. Is it left over from the beta? However, the weapons are working fine on original maps like "Operation Metro," so everyone enjoy what they can until the fix comes.
