I am currently stuck on level 8 and cannot upgrade to level 9. I have well over 200+ skeletons to upgrade but the when I click on "DONE" it says I do not have enough doughnuts. IS there a clitch? I tried going to Krustyland and back to sync and even went to a friends springfield and back, with no results. Anyone else having this issue?
