Pls help! Can't collect mini-kit

[Dark Mi5t]

On Episode 6-5, Jedi Destiny, there's a mini kit I can't collect.
Its the one you have to assemble after using C-3PO on a door lock.
After my character has built it, it floats up and off the screen!
Any one had this prob or knows how to solve it?
Cheers

***sorted it, damn glitch***

You don't have to get all of the minikits in a single play-through. You can go back as many times as you want/need to in order to collect all of the minikits.
