"A Healthy Improvement" companion quest bugged.

[rump]

I received the task to "retrieve the Dematerializer", which I can see, but cannot interact with. As a result, I am unable to continue not only this companion quest, but unable to open any further lockboxes. As such, it seems this bug affects multiple parts of the game, and it would be great if anyone knew a fix, or if this could get patched so it would work again.
