Injected records in overhauls are not copied as standalone

This was demonstrated with Citizens of Tamriel, and CoT-Visual Overhaul. The output in xEdit looks like:

The overhaul proved to have invalid overrides (aka "injected records"):

Needs some testing to determine exactly what happened, but my guess is that EasyNPC thought that the record actually came from the master (maybe because it looks at FormKey.ModKey) rather than the overhaul, and therefore didn't copy the record, just referenced the false master which became an invalid reference once the overhaul was deactivated.

If the above is the case, then the Record Importer may need some tweaking in the "master contains" logic to check that the master actually really contains that record.

This was also shown to happen in the 3DNPC Visual Overhaul, which is actually one of the mods with official mugshots.
