Finally, version 0.15 is finished. It has a children evac code modification so the children et gets spawned over and over again if it's destroyed, mountain cells are corrected, blight is on double speed, a little number of fixed beacons are placed, and disasters are cumulative(start weak and grow over time. Of cause, there's a maximum). Last but not least, the third AI base works. I don't recommend destroying it since it doesn't attack, it is capable of rebuilding the main base and shortens the time until the children et is build.
