GrassGames Twenty

In the card game Twenty, it used to be that you could move a card from one foundation pile to the other if the card was directly ascending or descending of the card in the other foundation pile. A couple of weeks ago while playing it would not allow me to do that. Then it switched back and you could do it. Now it is locked up again. Any information on what is going on with that or suggestions? Thank you.
