Whenever I try to add new layers to a map, the new layers appear on the Table of Contents, but they do not render in the map. It seems that I'm unable to view the new layers after I've added a basemap. Anything added before the basemap is visible, but nothing added after is. I need the basemaps because I need to georeference tif files. I know the layers work, because I can open them in new files just fine. If I try zooming to the new layer, the map goes somewhere, but there is nothing visible. The new layer sin questions are XY data from an excel spreadsheet (with proper coordinates) and tif files (that I subsequently georeference).
If at all possible, I'd rather not have to make a new file each time I need to add a layer.
