Upon release, Black Ops II patch 1.13 has been causing players a lot of issues, with most of them reporting the inability to find any new personalization packs after going through the hassle of downloading them. Good thing is, Treyarch is working on a fix, and has been sending out messages via twitter.
“If the game is telling you that you don’t have a DLC or Personalization pack, but you know you do, you don’t need to reload it,” Treyarch game design director David Vonderhaar said. ”This is more likely to happen with people who have a lot of DLC or micro-trans. The game takes time to mount it all. (Like sticking a thumb drive in a USB slot on a computer.) If you wait a minute the game will catch up and show your DLC and MTX.”
He added: “We are working on a hotfix to give the game more time to discover all the content you own before you go into Xbox Live.”
Patch 1.13 was supposed to fix a myriad of issues instead of causing them, including nerfing several weapons. See patch notes of said patch here.
