The short answer is that multiple people have done one run of glitchless making up their own rules for what a "glitch" is, nobody really likes it, and nobody really wants to run it again, so there hasn't historically been any point in making a leaderboard category.
Not that I can think of. Just make sure your submission shows either a fresh profile being created or resetting the campaign from an existing profile.
If you’re on PS5, the cutscene fast forward is a known glitch.
If you were able to do this while still having game audio, or if you did it on any other platform other than PS5, we’re very interested in seeing any clips you have.
In any category where I have WR, if I display the WR Information panel in LiveSplit it says "World Record is X by BinksMagnus" as opposed to by "me."
The only way I've found to fix it is to begin the process of submitting the run to SRC, input my API key, and then back out. This fixes the problem across all Split files until I close and reopen LiveSplit.
Not sure if this is a bug or gap in functionality but no one else I've spoken to has encountered it. Checking to see if anyone else knows of a fix (or maybe something silly I've done) before I submit a bug report.
