I just ran Portal again and recorded demos but for some reason it's writing data as if I'm playing on a mod (ex. from sourcemods folder), so when I playback the demo it says "directories don't match (portal / mod)" But it's running with nothing that's loaded from an external gamedir.
Okay, apparently this was because of the demoheader.tmp still containing data linking to the mod that was interfering. So I deleted it, created a new one and it works now. I guess let this be a precaution or requirement so people who both speedrun and play mods know what to do when trying to record demos or something. I hope I can also recover my demos if it's safe to replace the old header with a non-mod one.
It was recently discovered that it is possible to set your mouse sensitivity to a value so high that the game considers it infinite, leading to several new glitchy techniques being discovered.
The rules have now been amended to ban these new techniques in both Inbounds No SLA Legacy and Glitchless.
