Ah... that's no good. Alright, we'll add it to the areas for testing performance. We recommend in the meantime that you try closing the game, leaving it off for a while, then retrying to see if this happens again or not.
I know it's not a great fix but sometimes the game runs up a lot of memory and you just need to close and re-open it every now and then... doing our best to try and look into a fix.
