1. What happened
Importing this specific file results in a bad pose and in consequence a bad Humanoid Configurarion and messed-up animation.

Open attached project
note: project contains the same file, two times, each showing the issue a little differently. Same file, same bug, two different bad results.

Open file in 5.1 ... all good.
This happened on 1/200 files tested, but don't understand why this file doesn't import properly.
