Sadly, but gotta downgrade version because of infinite bombing attack on same base. And I just getting message about it without any ship on sonar. May be it's affected by chance of detection but aliens should forget about base location after they successfully bombed the base to give player chance for rebuild. For now I don't know how protect the base from invite loop of attacks. It's just sucking money for repair. And one more technical moment. If you start play this version on OXCE 6.4.2 or early, upgrading to 6.5 will produce segmentation fault crash if you try load old save file. May be save format was changed, I don't know.
