At the beginning of a live chess match, I found that one of my bishops was in place of the opponent's bishop at f1, and that it had disappeared from its original position. Later, the opponent seemed to move out his bishop from "under" my own bishop that was somehow stranded in his territory. I could drag my bishop around, but dragging it around had no effect; it just returned to f1. I also tried clicking the place where it should have been, but this had no effect either.

I lost the game as a result of being unable to use my bishop. Here is a screenshot of what it looked like when my opponent castled, putting his rook where my "ghost bishop" was:
