Gingerbread house stop upgrading....

I feel annoyed about this too. I was hoping to just finish it off but yesterday when I was completing the last task of level 4 it went back to the first task of level 4. If it had completed and I'd gone on to the final level I might have finished or, at the very least, needed a much lower number of donuts to complete.

It's a small thing though and my life isn't worth wasting on communicating with the help chat. (Wish we could actually speak to someone like US customers.)
