Help with Pose Pack?

I’m not sure if anyone will be able to help me, but I was trying to create a pose pack in Blender using a tutorial here. It looked great in Blender, but when I placed them in-game, none of the sims moved to where they were supposed to go, and one sim was even sideways in the ground!

I have no idea what I could have possibly done wrong.

In Game:

Thank you to anyone who may be able to help me!
