yeah @waylow I think you are right there. When I added in another new bone in that file and used the plugin, it worked fine. But just wouldn’t work on the existing armature. its so weird. Opened up other rigs as well from earlier blender builds and they work fine.
So I think it must be a problem with the 2.92 version or blender that is messing it up. ah well, wont take long for me to rebuild it in 2.93
