Cruiser Command

I have mess with the core, im the power guy. I have put it to 105 before, but as u can see. when my rep was in the neg. I was unable to increase the core. I have lowered the core to 60% before when it was unstable during battles. We won, and i dropped 20 rep. currently at neg 40

I was at 10, then neg 6, then neg 21, now neg 43. Every time i win, i lose rep. I usually control power, nav, weapons, mining...
