play yourself!?

I had issued a challenge for a 2 min Bullet game (Casual) and when I clicked on it once again to cancel it, it showed me as the opponent! Was logged in through only one device, so not sure how this happened.

Check this - it shows my name in both Black and White.

This doesn't happen all the time, though. So it must be an erratic bug.
