In my opinion, life support do not reflect the actual limitation for range.
First of all, ship never need to resupply at any base.
Second, when thrown away far out of 'supply' range, the ship do not die, it race back in controlled space.
So in good roleplay, I prefere the ´I cant communicate with central command' past this point.
It could also be a nice twist if any scouted area outside of command zone where only updated when the ship return in command zone!
I can imagine my explorer comming back home with tones of new info after the wormhole exploration.
Also, if experience is ever coming back, High level captaine might make little detour on the way home getting more info and more anomaly (wich would only be made available when back in command zone)
Any thought?
