A card is "unknown" by the game

I don't know how to reproduce this. I'm not really sure what I did to get this state and I'm not sure how to describe it as well.

The good point of this ticket is that it has a video that explain it better than me. I realized of this behavior and I used recordmydesktop to record this because I didn't know what I had done :)

I hope it helps.

In my debugging, I have occasionally gotten myself into a state where it thinks that a card is in the match area (left) when it is actually in the grid, hence it reports a bad match even when it appears that there are only two cards in the match area. Thought it was a transient problem but apparently not. Will try to reproduce it.

The attached image illustrates the problem, I repeatedly dragged the red O on and off of the match area with a rapid motion and finally managed to get it back to the grid without removing it from the match area as far as the internals of the program are concerned.

Good! You find how to reproduce it. I tested what you said and I could reproduce it again: dragging repeatedly one card on and off...

I think I nailed this one with [1]

Sound be fixed in v39. Please reopen if you can reproduce the error.
