On February 19,Call of Duty: Modern Warfarereceived a patch that addressed some of the game’s lingering technical issues, including theJockworth Gunfight bug. However, it seems that the update has caused some new issues to arise in the popular first-person shooter, with some players now reporting that their perks are simply not working as intended.

Reddit user -Stun- posted to Reddit about their Quick Fix perk not working inCall of Duty: Modern Warfare. InModern Warfare, Quick Fix is supposed to heal the player instantly, but it simply didn’t work when Stun attempted to use it. There are guns in the game that can delay health regeneration, but other users have reported the same problem as Stun, meaning that this is more likely a bug than just a misunderstanding.
