After the latest patch, is this enabled or disabled in the exe in vanilla? Can someone confirm? I tampered with mine but I want to return it to vanilla.

If you want to return it to vanilla, just open the Exe again, and untick everything.

My guess is the settings would have been replaced when the executable itself was replaced.
