Hello, I'm not sure if this is the right place to ask this type of question, but I've been getting a weird problem in ArcMap 10.5 that I can't find a lot of information about. When I rotate my data frame, after various amounts of panning around, the data frame resets to the default rotation and the basemap completely disappears. It's still in the table of contents and the checkbox can still be checked but the only fix I've found is to remove the basemap and just move it back in from the catalog. Is there something I'm doing wrong? I tried to create a completely new .mxd but the same problem happens. Any help would be greatly appreciated, thank you!
