Crazy Machines Fanpage Board

I have completed level 58 of new challenges (with help of some screen shots I found on this site! but even with the hot dog roasting, and the gravity going on and off, it doesn't show up as complete.

Any thoughts? What am I doing wrong?

Thanks for any help!

[EDIT: turns out it was a bug. I restarted the program and the most basic of solutions that I had tried AGES ago, worked fine Try that if this happens to you!!]
