There is bug in the program when spades is called

I play my game of spades regularly. I enjoy this game it provides me with the challenges of keeping my mind occupied. However there are mistakes and bugs that need to be fixed. When spades is called for there are several times but I have noticed that the opponent "the computer" does not always play spades and they have some in their hand because they play later. This needs to be addressed seriously. As I stated I played this game a lot and this has happened approximately four or five times. This bug needs to be fixed please thank you. Toumachine
