I know there is something you need to do with the files for sourcesplit. I saw Can't even do that on a stream the other day but I have no idea what that is. I had just finished a run with a decent 02 skip (for me) to then realise that it didn't end. The only threads I found just said "Nevermind, I fixed it."
To provide an answer that might actually be helpful, use the "bootleg" version of SourceSplit, which is pinned in #general in the discord ( https://cdn.discordapp.com/attachments/305456639530500096/694295551331663883/LiveSplit.BootlegSplit.dll ). Put it in LiveSplit\Components, and then in livesplit go to edit layout → add new → Control → SourceSplit Bootleg Edition. Also deactivate sourcesplit otherwise it'll split twice.
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.
