Early this morning I uploaded this map:

Clearly buttoning everything up at 1AM was a bad idea because I forgot to put the custom sky texture in the zip.
I don't see any option to delete the map so I can reupload it and I don't see any option after hitting the edit button to upload a new .zip with the required files.
