Hello- I'm having an issue with my Encore Megatron. I don't know if anyone else is having the same problem, so I thought I'd try my luck... The point where his upper thighs meet his "hips" is a swivel joint, he can either lean foward or way back. On the original G1 toy this swivel was kept on by a screw, on the Encore it's a... rivet, or something? So right out of the box the legs were borderline "floppy". Over the course of time, just by standing there, the weight of his upper body causes him to start to lean back... I can count on one hand how many times it was transformed. My question is... Is there a way to tighten this joint so there is no more leaning? With the screw it was a simple matter of tightening it, but with no screw I'm at a loss at how I could accomplish this... Thanks!
