Hi everyone, Z here once again. This time, it's some news!
Today DICE posted a Battlelog announcement saying that a fix is inbound for the MG36 and QBU-88 bug on Back to Karkand maps. The fix will be included in a new version of the Back to Karkand DLC which will be made available tomorrow (13th March 2012). The fix is applied by re-downloading the DLC.
At the time of writing, this has only been confirmed for the PS3 system.
This fix relates to a confirmed bug with two DLC weapons (the MG36 and QBU-88) that are displayed incorrectly whilst playing on the Back to Karkand maps. The weapon and arms models are misaligned - much higher than for other weapons - blocking the player's view, even when aiming down sights, making kills very difficult.
Here's hoping with the announcement of this fix and with the recent server-side updates, we'll get to hear and ETA for the next major patch soon.
