I tried to hack an Advanced Research Station. I built the Scientific vessel that's used for hacking, moved it to that planet with the help of a cloaking starship. The hacking vessel got damaged but survived and I moved it out of reach. So it started hacking, while being cloaked.
After 10 minutes, it had completed it's hacking. I could click the Hacking vessel, find the ARF tab, but the buttons were greyed out and I did not find a way to 'steal a vessel blueprint' so to say.
Didn't have much time to figure it out, as suddenly I noticed a MKIII Raid starship nibbling at my home base, obliterating me within a moments notice. So I wonder, what did I miss when I tried to hack the Advanced Research Station?
