I've had this problem for awhile with this one map. I have a background for a guest difficulty and one for the rest of the difficulties, but every time I (full)submit it it prompts me that the background I don't have in the map I'm updating is not being used and asks me if I want to remove it. But it is being used by the other map. It will state that for both background images depending on which map I'm in when I submit.
If this is a bug, please confirm it. If not tell me how to fix it.
