Bug: mobile orbital nulifers dont work

In escalation i watched as ai dropped several orbitals on my army when it had 12 orbital nulifers protecting it..  #pointless

also you can still drop the nuke down near the edge of a nulifer and take out half of what the nulifer is protecting.... again pointless.

both issues need addressing.. if you have anything under the circle of a nulifer it should be protected until something takes out the nuilfer.  its as simple as that.
