It's been reported that a glitch in Metal Gear Solid 2: Substance on PC has been inexplicably patched out, but not because of an update to the game. Instead, it seems that it could be the result of a Windows 11 update, and I'm just as confused as you are.
As shared by speedrunner @ApacheSmash on Twitter, the glitch in question revolves around pushing poor Emma Emmerich out of bounds in the air purification room on the first floor of Shell 2 Core, as well as the KL connecting bridge. After sending her through the walls, reloading the rooms takes Emma on a very handy journey through time and space, warping her further into the level without you having to drag her there yourself. While each of these skips only shaves off a few seconds, in a speedrun, every second helps, so you can imagine that some speedrunners feeling a little ticked off to find that it apparently no longer works on Windows 11.
