The reason you need to uncheck follow origins is because the dependencies are baked into the clothing when you copy from the regular figure in the scene. When the morph is applied the origins and scales are already matched.Then they get matched again by the included in conforming options and it explodes. If you copy from a developer rig they don't have the dependencies setup. You're clothing will need "Follow origins" checked like is normally expected. You should get a better morph transfer too as the dev rigs have a higher resolution base mesh.

This is why we still need developer rigs.
