So I've seen some players portaling under themselves (with the corefall strat) after incinerating all cores, which puts them out of bounds. I missed one core, so I portaled under myself to grab it and put it into incinerator. Does this invalidate my inbounds run?

that area is inside of a larger room, so its perfectly inbounds. run is still valid

Thank you, but in the meantime I got another PB without screwing up the corefall skip :))
