Chop Sorry, I can't load the save game. It complains about a double key which shouldn't happen. (I think this is another game bug).
As to the problem at hand I can only guess from the image. Having the ship would be better. Anyhow, I think the problem is you have the whole ship covered in emitters and only 3? cores?
The more emitters you have the less recharge will be transmitted. The recharge is divided by the number of emitters. So you need to use more cores (which can by buffed by gravity generators). I think twelve emitters is roughly even with vanilla. The system changes based on available power.
Right now the cores use very little power which I'll probably raise once I figure out better balance numbers. It's difficult because if it where 1:1 it would be impossible to power while anything less is OP.
