IIRC, I've seen something similar working in saved scenes, where objects with individual origins at 0/0/0 get positioned per scene. I do a lot of porting from DS format, and it's one of the factors that can thwart conversion...

Um, if you move object away from 0/0/0 then save, thus offset, to library, what happens when you re-load ??

( Currently hacking simple MMD PMX objects' pose files as possible fix for PMX Editor's bone transformation window that does not seem to offer numeric display or input of rotation angle. Have finally figured how to 'bake in' such changes prior to export as OBJ+MTL, but must twirl 'by eye', rather than set eg 45º. Happily, like OBJ+MTL, VMD files are plain-text...)
