Server Error uploading to gallery/library

Hello,

Since last year, I've been trying to remove some of my old creations that were uploaded to the gallery a long time ago. One of them is a build that I created in 2016 and it received a Maxis favourite right after I uploaded it.

This is what always happens. Whenever I try to delete these particular creations, the game show me this message: "Server error. We could not process this Gallery request. Please try again later." After receiving it, the creations stay hidden until they reappear in a few days.

I really don't know what else I can do to make them gone permanently. I actually just deleted them again an hour ago so right now, anyone who is reading this probably won't be able to find them but one thing's for sure, they will always come back.

Please help.
