The Import > Feature Class (multiple) option of ArcMap is not loading all my features. When I do this it fails and only loads partial features (only 200k features instead of the full 800k). When I do Import Single Feature it runs with no problems. It is a basic shapefile import to a geodatabase feature class.
I have been doing this type of import for years with no problems and now out of nowhere it seems to be causing me trouble, slowing down my monthly data updates.
Why might this be happening on the import multiple features only?
