See, I dont get that. I have 4...FOUR units athat are fine, and like graham i take em through their paces. I play with my toys. i have heard you talking aboiut getting this magical confirmation about the shoulders....dude, telling us on here won't get you the answer. I dont know who you have to ask but it isn't us!
I'm sorry yours has a broken shoulder, I truly am. If you dont want to buy more of the toy, thats fine, and thats your call. But after several versions now that arent having the problem, you either need to accept it isnt there, or move on and not buy anymore!
