Hi,
i got a short question. when playing solo-mode against the computer, is there a way to build a planet in such way, that the computer cannot just warp-through it to your other planets ? for example, is there some blocking shield or something you could buy, or somehow force the computer to first destroy this planet and my fleets there before he can pass through deeper into my realm ?
And can i modify a file somewhere to raise the logistics slot cap beyond 24, or decrease the amount of slots certain building use ?
any helpfull answers appreciated 
thanks !
