UPD 25.02: Autosplitter was approved and added to the LiveSplit database

To use autosplitter you need to go to Edit Splits and press Activate

If you don't want to set up splits like i do - you're free to do so, just untick the Split in the splitter settings. You'll still get autostart and IGT features

If you want to - you need 4 splits for any campaign run, 13 for any%, and 26 for all campaigns.
