Will do my best to explain this . . .
Started a new game. About 3,000 or so in I had a fairly decent chain going -- probably around 5 or 6 red squares. I got a picture text. I looked at it for a second, then hit close on the text without leaving geoSpark. Hit play to resume game after text closed. My chain was stopped in place where I had left it, so I tapped it. The shapes dissapeared and I gotbly points, but the gravitational pull of the chain remained stuck in the same place. No ammount of shape popping elsewhere on the screen would make it go away. I tried to take multiple screens, but only managed to take one before losing the game, so it doesn't do much good.
Thankfully I was on a fresh game . . . This could really suck otherwise. Unintended pun.
You should follow me on twitter here!
I also have discovered the same issue; it seems to occur with all UIAlertViews that display. When you touch to dismiss them, it creates a gravitational pull where you touched that never goes away. This could be an awesome "Extreme" difficulty mode, but I want extra points for it if I play that way. :-)
