This results in entire animation being broken, so model just T-poses whenever this broken animation plays.
Log: https://gist.github.com/NordAct/39437306645af60edee5e1ea9eaa1685
Problematic animation and respective model files:

1. Animation | Model
2. Animation | Model
3. Animation | Model

Also want to suggest to add resource location of animation file in error print for easier identification which one exactly is broken

There's always some edge cases that my testing misses :(
