Here's one error. It showed up after I went back to my Charity hair file. I started the process, but set Charity as extension rather than neighborhood... and it gave me the No Obj Found error too! It's spreading! >.>

But it seemed to complete anyhow? The Obj Not Found error seems to come AS the Import Obj dialogs are happening so I wonder if that's a sequencing thing.

Anyhow, it seemed accessible and complete so I went to do the Hair Attachment stage but as soon as I touched the Presets, the below happened. Maybe just because it had already failed earlier. Dunno.
