game_over() cancel previous put() actions #250

Hi,

If I change a piece on the board with a chess.put() I see that the board is being changed correctly when i do a chess.ascii().

But then any call to check chess.game_over() will cancel the last put action. This problem occurred on a queen that I changed for a rook after a promotion on last row.

I bypass the problem by doing a chess.load(chess.getfen()) after each chess.put(). But this temporary fix is cpu intensive.

Many thanks for reading me.

sounds related to the bug mentioned in the docs: "The en passant square and castling flags aren't adjusted when using the put/remove functions (workaround: use .load() instead)"
