Call of Duty: Vanguard's previously scheduled December 9 weapon tuning pass has been delayed, as patch notes arrive for a small hotfix to address bug fixes and spawn adjustments. Sledgehammer Games says the weapon changes were postponed to maintain stability.

Originally, the December 9 update was meant to include multiplayer weapon balancing for Vanguard's tactical rifles, sniper rifles, and shotguns. Instead, the update now brings adjusted spawn logic to reduce spawn traps on Shipment and updates to the Mortar Barrage killstreak. Previously, the Mortar Barrage caused major visibility issues for players, but the update brings improved visibility by reducing full-screen smoke effects. As a result of the change, players need to be closer to the barrage to be affected.

This update should bring more stability to Vanguard as Sledgehammer Games says the "Server Snapshot Error" bug that resulted in players being kicked from matches has now been fixed. An update also arrives to the Clan feature, as banning users from Clans no longer results in an error.
