Alright, maybe I've been dabbing a bit much in the custom quests, but this even fails on a 1.90 quest, Quest for Freedom.

Simply get a triforce piece on any standard quest. Normally, you'd warp out of the dungeon. However, you just get placed...right where you picked up the triforce piece.
[Edit that's not an edit]I just tested this on the First Quest. This same behavior shows. I believe this is a bug now.[/Edit that's not an edit]
