Card stayed open and blocked most of the screen

Zaphod

Hi,

I was winning until this card (Trostani Discordant) stayed up on the screen and never closed.  Additional cards opened and closed as the game progressed, but I could only match the gems I could see.  Everytime I tapped on the card the artwork expanded, but the card would not move or close.  

I have a screen shot, but I dont have a url to use to attach it.
