Well, just tell me how to disable it. I dont mind if it can be fixed or not. I checked scripts but i got confused. I donno what to do and didnt wanted to delete everything related to "wall".
As pointed at topic, I quite dislike wall building AI. How can I forbit AI from building walls ever ? Maybe it could be worked better if there would be a rule that forbits AI from building walls outside a fixed radius from his first TC and/or building walls so close to others bases. Another thing ...
