Transformers Animated Prime Problem :( Help

[Zaul]

I purchased the Transformers Voyager Optimus Prime as it looked like a much nicer figure than the huge one.

However after transforming mine i've found his upper torso and waste is very lose, even when posing him his upper body turns left and right very very easily, a small breeze would rotate him 360.

Is anyone else having this problem? I like the figure but I really hate the auto morph feature or whatever its called on this, the rotation on mine is just stupid.

( Yes I've pushed the torso down to get the click so the automorph feature doesnt work anymore, but he's still loose. )
