I've captured an NPC base and I want to take it over completely. Most importantly - I want to steal the contents of 4 large hydrogen tanks which I can't grind down to claim ownership without spilling the previous contents.

So I place down a hacking computer on the target grid, but it doesn't do anything. Status colour is red. I know it has power. I've tried grinding off the tanks on to a separate grid and attatching a few wind turbines, and that hasn't worked either, as well as rebuilding the computer and turning it off and on again. Still no hacking.

Am I missing anything obvious? Are there mod conflicts that don't play nice? E.g. I have the Easy NPC takeovers mod as well, but I can't find the remote control block on this grid.
