The Energon Pub

So I've finally gotten around to digging through my closet and opening some items I've had sitting around for a while. Came across this set which seems to be burdened with senselessly flexible joints, made of completely inappropriate plastic/rubber. From looking around the web, it seems that this is a largely endemic issue. Does anyone know if it's the case across the board with these figures, or if a running change was made along the way, to tighten things up?

The "First Aid" in the set using the PRiD Ratchet mold had those weird soft joints. Everything else was unchanged from initial releases of the molds (plastic type wise).
