Exploits exist apparently

I was playing with another person and about to finish the game and my bishop wont take their queen. It is an entirely legal move and yet it wont register. I have flagged the game as "possible cheat" and the game hasnt been reviewed. I realize there is no liability for them to review the games for cheaters per the TOS but this isnt much fun.
