When you mouse over a system in the galaxy map you have an option to buy the system data
As i sead its not like in beta, in beta you could buy system data and get the full info, now as I write this I cant even buy system data from a system 5ly from me and yet when I warp in I "discover" objects.
I dont really like to be forced to explore to obtain data when in beta you could buy it.
So why this change, I mean we have 400 billions of star system and still I have to explore known systems.
It's like going to school in Sweden for an example for 10 years and have no clue how Denmark looks like.
