So since we don't need a new file for Sides Any% runs, it makes the most sense to use a 100% complete file for Yellow Sticker movement in the hub, right?

Never even thought about that! but yeah, I think thats thats fine to use sticker abilities in the hub. alternatively, abilities could be banned in the hub. what are your thoughts / preference? edit: I think less restrictions is better

Yeah I think if the sides category is supposed to be mostly about level execution, it makes sense to allow yellow sticker movement

Agreed, lets keep the rules as is then. :)
