I got the Shadow Commander trailer 3rd party thing (the Nemesis Prime version of the City Commander set) Overall I'm happy with it, however I ran into something unusual. While trying to put the arm/gauntlet pieces on again, apparently I was mixing the arms up (I was trying to do it without directions to see if I memorized it) I heard something snap, a tiny like flap came out. After looking at a picture for reference I realized I had mixed them up and proceeded to take the other one off, when a similar tab piece came out of the other one. Now heres the weird thing, neither piece appears to have had any type of stress marks or breakage points on it from what I can tell, in other wards it looks like maybe those tab may have been in a slot and just fell out? The arm/gauntlet pieces still seem to fit on ok so its nothing major, just wondering if anyone else has had this problem or knows what I'm talking about?
