In TFT, I was doing a level and I had to save and exit of it. When I came back, the power tiles disappeared! Fortunately, they reappeared in the next level.

I haven't tried it again, so I don't know if it always happens or you just have to save and exit to cause the glitch. It was there in the 3.1 update, and this occurs upon exiting and entering; this will occur in all levels where Power Tiles can appear.

Also, the PTs are still there, but they're invisible.
