I have been working with some GIS data in the form of SHP files in autocad map 3D 2014. On one of my layers I have started getting "Feature was not saved in the targer feature source" when I try to check in my data. In total there are 20 errors in the data table, all of which were features I deleted. They all have a featID of null and I cannot remove them from the data table. I need to fix these errors without going back and starting over. Any ideas?
