With Call of Duty: Black Ops Cold War’s last update leading to a handful of game-breaking bugs, developer Treyarch has dropped another patch only 24 hours later in hopes of raising its quality of life. Aside from fixes, it surprisingly also adds the Miami map to the 12v12 Combined Arms playlist.

Most notably, this patch looks to resolve newfound map voting errors, along with certain maps not appearing in specific playlists. However, this will not fix the popular “Blackout Trial has ended” bug on Xbox, but Treyarch has stated on its website that it is “tracking” the issue.
