Hi Crapshoot, thanks for your advice. I was really loading a timestamped nav file which I thought was the new one but in fact was the old file. lol..now i got the nav file updated but the axis bots complains to have no goals after the radio room door is constructed. I was trying to toggle on the defend/camp actions after door is built. it seems like the map actions does not respond to the keywords in the aiscript. could u pls take a look at my aiscript and nav and see whats wrong? I hate to bother u with so many questions but I need your expertise.

thanks a lot!
