Hi Scratch Team,
I've been having a few problems with studio thumnails and profile pictures lately.

My alt account, @BananaBall_alt, has a profile picture, but it only has the default profile picture.

A studio that I manage, Project Help, has a thumbnail, but on my profile it just has the default thumbnail.

Also, with some projects, the thumbnail of the projects just are gray.

Please fix these so that my profile picture is recovered. Thank you!
