Hi @BillSr !
Sometimes the descent into black is from how many of us Nodders are accessing the maps. Usually, if we give it a break, the server unscrambles itself. Try back in a little while.
I also find that if I wait, sometimes the image will come in. But if two or three all load to black, I just close up shop for a while and come back later.
Oh, by the way, for server or image issues, look to see if others reported a problem and post a reply to that thread, or start one with the subject "Bug the Campaign then the problem". That makes it easy for Staff to notice bug reports.
Gonna go eat. "See ya" back later, I hope.
