This is frustrating because this is something I've done a thousand times before. However, I have a feature class called Parcels and I'm joining it to an assessment table based on a common field called parcel number. In ArcMap, it works fine. When I export the table, or export a subset selection, the table columns are all <null> in the exported FC. It does the same thing when I create a layer based off of a selection. It exports field names, but not the data in them.
I've recently just upgraded to 10.3, so I'm not sure if this is a bug therefrom, or I'm just missing something.
