My internet went out and when it came back on, trying to load my map only resulted in a forever "retrieving data" loop. I was really freaking out, but hard resetting my console and unplugging it helped it come back after relaunching everything. If this happens to you, try what I did rather than just deleting what is seemingly a corrupt file.
yeah i had same issue. one way around it is have a friend find it on your profile and then load it from there
