Hi Alex. It sounds like you are linking in the character using Library Overrides and not the Proxy way of linking.
In my opinion, the Proxy way is far less buggy than Library Overrides. The latter was meant to be production ready by 2.82 although it still isn’t quite there yet. There are many things that can’t be overridden yet (like constraints)
So I would suggest sticking with the Proxy way for the time being. I believe that is shown in the main part of this recorded course.
