Lost a two bomb run to not using autosplitter, I cannot for the life of me figure out how to use this thing. When I download the any% files in resources it downloads as an lss but its looking for an asl file.

ASS files are Split files, you're trying to load a layout perhaps? Also, you can check the Guides section for a video guide on how to setup the autosplitter <-- Guides should be somewhere here

I've got the auto splitter on now but as soon as I finish the Mr. Krabs dialogue it instantly splits every split there is and ends the run, its looking like I'm going to have to manually split because this thing is making it literally unplayable, just killing runs every time for no reason.
