The title says it all. Never got MP11 because I love my MP8 and MP7 (alt modes are the most important thing to me. I don't care about toon accuracy as long as the robot looks good and MP7/8 are just on another level).
However yesterday I picked Thundercracker from the shelf and to my horror found two scratches on his skirt pieces. They are on the underside at about 1/4 the length of the skirt pieces from the bottom and on BOTH sides.
I kept thinking and thinking but I can't figure out how it happened. If it was while posing the legs and they got scratched with the center piece on his back or the wings the scratches would have been on the top part of the skirt pieces and if it was against the wall they would be at the very bottom (I keep them horizontal so they are not visible from the front when the seeker is in robot mode).
