[NRVR-Members] Adding Nose Weight in OpenRocket

On the design tree on the upper left you may see mass and/or CG symbols on any level. If those symbols are on a level it means a mass and/or CG override has been applied at that level. In your tree I see a CG override at the "stage" level, so that's locking in the CG for the whole the rocket. Eliminating that should make the CG track changes. Alternatively you could just modify that to match reality.
And yes, I slammed my head into the keyboard for a while with the exact same problem.

Is there some magic button somewhere that "applies" it to the new CG calculation? I even played with the override CG buttons (though that needs to be a DEPENDANT variable.. I don't want to SET it).. but still can't get the CG to budge.
