It sounds like you physically can’t reach the HV to repair it? If the core is still in it, you can try to use cb:getshiphere:id to move it to you, somewhere near the pole edge. Replace id with the id number of the HV, which you can find on HWS Connect Structure Commander. Hopefully, that works for you, if you can get within 200m of where it is.
I can also spawn you an HV that I use for the Protoz Raid mission, if you’d like.
