From now on the timer must be included in any video you intend to submit as a time. You must also include the selection of a chapter you are playing if you are doing an IL run, aswell as the loading screen into the next level.

I found a way using some livesplit mods that will cut out loading screens, but will not automatically split as of now (I'm an idiot and can't figure it out, but if you do, good for you). Go to the guides section to get more info.
