OK, so no negative value.
Thanks for the detailed information about activating cloaking, Imperator Fyron.
So no non-solar supply generator, better be lots of stars then
Do you know if a solar panel (generate supply from star) uses supply if a "Amount of supply used" is given ?
(to do like generate 1,000 supply /star, and spend 900 supply, so that only 100 is generated for 1 star, making system with no star very difficult to travel, and the one with 2 or 3 stars very effective)
