For some reason bubbles can trigger area transition save points and olmec save points, but not checkpoint stands. Abusing this mechanic can allow you to skip the Isle cut-scene, as shown in the video. Nothing else has been found with this yet but its possible that something could come up.

Showed this to the glitchless runners, and after some discussion it seems like this should be disallowed from solo glitchless since it uses multiple players in a solo category.

The rules already ban this from solo categories. ("one input device") However I thought it'd be worthwhile to post this here to hear people's opinions on this exploit in regards to Co-Op, and to document the exploit somewhere more visible.

I would also like to hear people's opinions on changing the name of "Glitchless" to "No Major Glitches", since the current glitchless category abuses the arena skip exploit in Serpent Temple.
