Changing character doesn't keep pose and expression

Hello Jeff and welcome to E-Learning Heroes :)

Thanks for contacting us to share what you are running into with your project.

I assume that you're using a photographic character? I'm experiencing the same behavior in a test file and I'm reporting this for our team to investigate. I am not seeing any reports of this behavior, so I do not have any workarounds to share at this time, but I will link this conversation to the report.
