Arm IK does not follow Spline IK Top
On latest RRM3 (I think, the version number hasn't changed the last several times) create a new rig with the biped template. Don't change anything, it's not necessary. Generate the rig. Select an arm and switch to IK mode. Change the IK control to follow Spline Top. Try and move Spline Top. The arm IK doesn't follow. Does not seem to be an issue with any of the other follow spaces or with the legs follow spaces, just the arms with Spline IK Top.

Good catch, thanks for letting me know! The latest download has a fix for it.
Once RRM3 is out of Beta, I will start adding version # changes with each release.
