Livesplit autosplitter is currently broken due to an update to a third party library that the autosplitter uses called asl-help which has broken it. If you've noticed autosplitter is not working this is why.

Zach (autosplitter creator) has posted a guide in Discord with a workaround for this that I have pinned. Please join the Discord and look in the announcements channel to find the fix.

You will manually need to set this up in the meantime for the autosplitter to work. Zach will push an update and notify everyone once the surrounding issues have been fixed.
