I just learned that you can infinitely scan for more resources with the HQ node, not sure if intended but makes sense at least for the early version of the game. Why does the general scanner stop? If you already have a means of infinite resources from an asteroid, you should probably allow it to continue like the HQ, maybe reduce the payout by 1% or something each tick, and maybe the scanner is 50% or even 10% as effective as the HQ scan each tick sense it's automatic.
This isn't important or anything just kind of odd mechanic interaction.
