I did my first run with livesplit and used the autosplitter and it worked perfectly but it didn't split at the end of the Joker fight. I tried manually splitting at the end too but that didn't work. Is there an explanation and/or a way to fix it?

Final split is manual. Idk why you manually splitting didn't work, make sure Global Hotkeys is on and that you run LiveSplit as administrator.

Thanks that worked, also very fast response thanks for that too
