Could be good, but glaring bugs ruin it

This game could be great, but the bugs got on my nerves for the last time. I have had kings move 2 squares to get out of trouble as if they were castling out of check, but the rook stays put. I promote a pawn to a queen to nullify a checkmate and it is still game over as if the queen was not in a position to stop it. Once promoted a pawn to a queen and when the other player took it with a rook, they just shared the space and the queen was not removes from the board. It doesnt seem to improve despite the numerous complaints. On to the next one.
