Quote - In the Material Room, under Preview.  Create a new rule with the name of the prop and delete the original.

Thanks for the quick answer. However it does not solve the problem. I think what's happening is that bagginsbill tries to prevent the VSS prop to synchronize itself. This would happen if it could synchronize props parented to a figure. However, it also limits the usability for certain props. I was wondering if there's a way around it, so that props (which are actors in python) can be synchronized.
