You could add a copy (cp) command to the .bat script before the start command to cover this. Just have it overwrite the LauncherPatcher.exe every time the game starts, or even use an if-statement to only do it if LauncherPatcher.exe is above a certain size (since the hacked version of LauncherPatcher.exe is only 118 KB). Not sure if they have that as part of KSSL. I lose any extra steam cmd line options, but I don't use any so that isn't an issue for me. Thanks for the link!
