@Ronin I think you may have taken the suggestion above incorrectly.
I am not understanding how you interpreted @Albertos advice but maybe here is some more information. If the target is moving the collision and rigid body must follow along with it. Static rigid bodies will stay in place. Not sure why this would be a complete rewrite of things as it is a simple selection in the editor for your item that will be moving. I think I remember we discussed this same issue in this post.
