Aaauuugh!! I was on track to a 300+ point victory, then got screwed over by the orb scroll. I had already found and marked the mimic with "11" so I could avoid it, but when I used the orb scroll it revealed the mimic's square as a chest and erased my marker. I clicked on the chest without checking and ended my run. So frustrating! I feel like the game shouldn't preserve your marker if you placed it on a treasure chest square, pretty unfair way to end the game.
