Try clearing the app cache and clear the data for it. I've had to do that a couple times since I started playing because it basically held on to garbage data.

If you're using an Android phone, clear the phone's default browser cache too. Mine is just called "browser" since I put Cyanogenmod on, not sure what stock ROMs really look like anymore.
