I don't run the game, but I do very much enjoy SBCG4AP. Due to Twitch's new policy they're implementing April 19th ( https://x.com/TwitchSupport/status/1892277199497043994 ), if a channel has over 100 hours of highlights and uploads total, Twitch will delete the least-viewed highlights/uploads to make all channels meet this 100 hour quota.
That being said, I went through the runs using the History button on the leaderboards, and downloaded all the runs (which were WR at some point) that were Twitch-only. The funny thing is, they were all from Jai_Heart (39 runs). There were a few that I just couldn't download from Twitch as they apparently no longer existed. Regardless, if Jai_Heart would like me to reupload them somewhere (providing those highlights, even if it's just some of them, get deleted, then please DM me on this website! Thank you!)
