Disable the Renegade Base

Vallis Point Mission to Disable the renegade base seems to not be finishable. It wants me to "Destroy the parked fighters, the base defenses and the hydrogen storage area."

I have...

Used by grinder to remove the hydrogen tanks completely and just to be thorough I removed the light armor blocks they were sitting on.

Ground the fighters down to mostly damaged chunks of spread out armor and pushed them out of the base onto the ground below.

Dismantled the turret, the battery and anything that remotely looked like a control station.

I've ground down about half of the base to piles of components I can't carry.

For the spirit of the mission, I've destroyed all their beds, chairs, sinks and toilets.

If I could have written graffiti on their few undamaged surfaces I would have done so to carry the message "OBEY THE CA" since clearly these guys didn't have proper licenses for all this stuff.

At no point has the mission provided any feedback about progress, and the waypoint for the mission is 80m underground inside solid rock. I drilled there just in case it wanted me to go to that point before doing anything else, but no luck. Then I fell through the earth and had to drill my way back to the overworld.
