you mean the whole extension and elbow pad support unit moves/rotates inwards and outwards (transverse plane) don't you? yep, i've seen it.
couldn't happen on the 114 as the elbow pads were essentially bolted to the basebar, not to a unit 'supported' by 2 long bolts.
apparently argon have a fix coming out very very soon.
