How do I unban a creation?

[DalekThatIsGood]

I didn't actually think that I had banned any creations. I must have done it accidentally when I was deleting something. A new Adventure that popped up in my recent downloads apparently has a banned thing in it. I wanna know what it is, but I can't find anything on YouTube or Sporepedia that might help me find what creations I have banned. Possible to unban?  Even if I can't unban them, is there any way to find what creations I've banned?

You never banned anything. The ban symbol on an adventure is different, an adventure gets the ban symbol whenever it has a creation in it that for some reason failed to load, and doesn't allow you to play the adventure. This can be caused by the creation having modded parts, a building being too flat (for some reason), a creation that is too complex, etc. 

Tl;dr This is an issue on the end of the adventure's creator. You didn't do anything wrong, and there isn't a way to fix it unless the creator of the adventure released a fixed version
