Can confirm this file wont load, however I have trouble loading it elsewhere, too (which makes me wonder if this is a valid or corrupt file... yes, I've read it reads well in FBX review...), so will look more into it

I was able to reproduce this as well. I manually checked the file to see if there were any mismatched faces (not having at least 3 vertices), and I could not find any that were (on the surface) incorrect.

There are 3612 vertices, but faces are referencing indices up to 7226 (the file is corrupt)
