when i Generate a new Game with Settings: ( from Screen "factorio1.jpg") Than the Aliens spawns near the starting point and the Alien bases is not very small, low and poor.
(See the Map and Screenshot on the Start) I can see that problem only with the settings from the 1. screenshot.
i have download the zipped version from factorio 0.7.0 64bit
I hope you can understand my gibberish.

greetings.
