Great game but has bugs – Gin Rummy - Online Card Game Review

I love this game but the same cards get laid down that was already played and you see one card discarded then pick it up and in your hand it is a totally different card than the one you chose. For example, I waited most of the game for a 3 of spades, my opponent laid it down. I picked it up and it turned into a 3 of clubs. I had discarded the 3 of clubs about 4 rounds earlier. This happens almost every game. This has caused me to lose several games. Please fix. Thanks
