I don’t know how or why it happened, but the last time I attempted the clock tower, instead of being teleported with the rest of the group, I was teleported to a spot in the puzzle well above the start point, but in the midst of the green fog. Before I could even move, I was teleported to the entrance again, but it was devoid of players, npcs or even the doorway out. After another moment, I was teleported again near the top, but on solid footing in the puzzle, in the green fog again, but it didn’t have any effect on me whatsoever. I also had my weapon and utility skills available, and was able to move about the puzzle without hassle.
Strangely enough, this was the only time the clock face actually worked for me, instead of teleporting me back to the entrance.
