Call of Duty: Vanguard's November 11 update addresses spawn issues and several bugged challenges, which are mentioned in the patch notes provided in the in-game menus. Additionally, Sledgehammer Games has provided some of the update highlights on Twitter.

This new update adjusts some spawns for the multiplayer maps Numa Numa and Desert Siege, but also works to address a few of Vanguard's bugged challenges. Many players have voiced frustration about in-game challenges that won't properly track, and while many weapon camo challenges still seem to be bugged, the November 11 patch notes confirm the developer has implemented a fix for the reticle challenges that were not tracking past the first challenge tier. The update also corrects the Field of View setting bug, which locked some players' Field of View slider and prevented them from adjusting their view.

The Zombies changes mentioned in the patch notes include a fix for an exploit that allowed players to get out of the map, and a bug that left players with a standard pistol when downed instead of their Pack-a-Punched pistol.
