So was getting a friend's shade (a piece of her soul) back, curing Tony's palladium poisoning, fixing the destroyed building on campus where the monolith now sits. Someone wished for a whisky fountain and it was gone at the next reset, so I'm not really sure what would have stuck around.
We did get two things out of it: 1. the knowledge that we go right back to where we were taken and 2. a disappearance notification system.
