Call of Duty: Warzone got another fix for its infinite stim glitch, thanks to a patch on Thursday.

In the Warzone midseason patch notes, Treyarch called out a new fix for the stim glitch, which allowed players to heal themselves over and over again. Apparently, this glitch was a product of players getting stuck in a “throwback state” after chucking a grenade back at opponents.

If this fix sounds familiar, it’s because it’s not the first time Treyarch have tried to solve this problem in the past month. On Jan. 13, Treyarch and Raven Software launched a patch to solve an identical glitch. But the glitch resurfaced after the original fix, frustrating players even more. Warzone’s latest patch should kill the glitch once and for all, but that’s also what we said last time, so only time will tell.

The midseason Warzone patch also adds a few other fixes for the game, like normalizing XP across the Kingslayer and Verdansk battle royale modes. The midseason patch is live now for all players.
