Hello. I bought a Gravity Bots Bumblebee for my son. However, he did something to it so that the chest plate piece wouldn't line up correctly when it converts to robot mode. It would sit at an angle. I took it apart to see if something got knocked out of place, but now am having trouble putting it back together again. Has anyone taken one of these apart and could provide any help? Thanks! EDIT: Nevermind... I figured it out. A little tricky lining up all the gears, but not too bad. Looks much better now.
