Brief bug summary: [Aspiring to Escape] quest will not complete despite rescuing Sky and taking him through the final floor. I end up back at the hideout without the quest being complete. To resume the quest, I have to forfeit and re-accept each time, but each time it takes me to the final checkpoint just beside the final portal. I've gone through it at least ten times but the quest will not complete. It's notable that it worked fine the first time on my Kanna mule with no issues.
Can't do anything with it from an existing account other than read the details. It says you can start it on a new account, but you can't actually do that.
