Many people including myself are having enough problems with this update in that sometimes the game image freezes for a few seconds , the music is absent warzone no sound in the main menu and classifications do not work
no music for me and armor mods don’t work.
The armour mods issue is bieng tracked in this topic currently, see the post from A Rock Launcher for a temporary work around 
Since the update my CSR ranks are all screwed up, can’t achieve any point
On custom games, I’m not spawning into the game at all on forge-made maps from another user. These maps I have had for a while, and I have not experienced this until the update
I’ve had issues with Warzone dropping matches since the update this week.
I can’t spawn in any forge maps, even with a resp point, so if I die or need to go, I can’t edit it anymore
I don’t know if I’m the only one, but before this last update I had already played my ten matches in arena swat and got ranked. After the update I noticed that my rank was gone, so I played one swat match but it didn’t count for the new ten matches I have to play again, which is dumb. Please fix this, just like my SR-80 pack that I never got to open (and anyone from 343 has helped me).
