All of my progress got erased.

My designs are still there but I don't have checkmarks on a lot of the levels even though I have beaten them all. Can you please fix it for me so that I can see other people's designs again?

Thanks.

In the meantime, just watch one design from each level until it wins

then you'll have all the menus back.
