I'm always getting an insufficient investment in Energy. I got a looot of investment on Metal Mines but that's pretty much it. I'm almost always with negative energy because of it.
Also, it doesn't seem to invest in technology. The only one that appears in the auto-list is the Computer one and it's rare. It never makes an astofisics or combat technologies investment, for example.
IMPORTANT!!! Any planet and moon must be with UNIC name! Avoid names with more than 1 word!!! OA can't save your fleets if planets and moons are with same names or/and the names are maded for more than 1 word!
