Battlefield 4's first non-exclusive expansion pack, China Rising, is being released today for Battlefield Premium members, and its launch is already causing technical issues for some players, according to a page on EA's support site.
China Rising is already available on Windows PC, Xbox 360 and Xbox One, and is being rolled out on PlayStation 3 and PlayStation 4. Developer EA DICE is releasing a patch for all platforms alongside China Rising, so players must download both items in order to play the expansion.
Some players are being dropped from servers "within seconds of joining" when they attempt to play China Rising, according to EA. It's an issue that DICE is aware of, and although the studio is already releasing a fix and "players should be noticing normal gameplay behavior soon," EA cautions that the solution will take a while to fully implement.
In addition, some players of the Xbox 360 version of Battlefield 4 are unable to join servers and play after installing China Rising. DICE is still investigating that problem.
Aside from the aforementioned issues, Battlefield 4 continues to suffer crashes on Xbox One and PlayStation 4; we've updated our review of the first-person shooter accordingly. An EA representative declined comment and pointed us to the game's support page.
