Battlefield 4 has been patched on both the game and server side for the launch of the Final Stand DLC today, and the list of fixes is extensive to say the least.
Battlefield 4's latest update comes with a set of patch notes so long I felt faint just thinking about formatting them for you, so instead here's a link to see them in situ on Battlelog.
If you can't bear trawling through them all, maybe just scroll down to the bottom for the list of platform-specific fixes, to see if you're favourite bug was caught.
I thought this server-side fix was particularly good, though:
"Fixed an issue where servers did not recognize more than 50 unlocks and therefore some players never got assignments, dog tags and other unlocks when they should have."
There's nothing more frustrating than not getting the stuff you've worked for, so good to see that one in the bag.
Battlefield 4: Final Stand is out now for Battlefield Premium members, while the rest of us need to wait until December 2.
