Sometimes some of the files making a shapefile get removed while others
are left. Exit from QGIS and delete all the files

C:\Users\scott\OneDrive\Desktop\Consulting\Acumen\Machine\Chris

Johnson_RG\swat9\Watershed\Shapes\drawoutlets_snap.* and restart
choosing the drawoutlets.shp as the inlets/outlets file.

For added security you could also delete all the files

C:\Users\scott\OneDrive\Desktop\Consulting\Acumen\Machine\Chris

Johnson_RG\swat9\Watershed\Shapes\drawoutlets.* as well if you are happy
to draw the outlet point again.
