The beginning of the vid is 9 seconds of a run that I reset. I had the same thought at first too but I think we're good! Maybe I should edit out part of the reset to make it less confusing.
Yo H2O! It should start automatically. Here's some things you can do to make sure its enabled properly:
Go into your splits editor and -Make sure the autosplitter is activated -Go into the settings for the autosplitter, and make sure start and split are both checked -make sure you have all the splits you wish the autosplitter to split checked (and no other splits)
If the load remover seems to not be working, make sure your timers and comparisons in livesplit are set to game time.
I hope this helps! Feel free to contact me on discord if you're still having trouble PeteSwanson#3946
