so I went to my first guardian site today and thought, while I'm here I might aswell get as many things as I can get (cause it's just a tad away from where I usually am....~30 jumps with a 30Ly jump range kinda of far away) did all the things, got the data and went at it again, I could scan the orb thingy but didnt get any more data. I thought "oh ok you can only get the data once, fair" how does the refresh work, can I just go to other sites to get more stuff and how long does it take to refresh?
