I've been playing single player (campaign).
Although I have 20 energy regeneration points per turn
, my energy bar was full after every turn, no matter how many energy points I've spent.
In every turn I've used drone Blue snow
which spends 9 energy per use
, side weapon Le Gun
which spends 8 energy per use
and Mach 2 Cannon
which spends 14 energy per use
I saw this happened, but I was not sure, so I've watched my energy bar throughout entire next single player battle and this occurred all the time.
Probably happened before, but I didn't pay attention.
