(If I had to guess, probably inconsistent PID and ACB variable loading causing the game to confuse the difference between -90 and +90 degree intervals. -or the actual game AI straight-up ignoring orders as usual.)

this is one of my favorite creations by you but unfortunately it seems the attack pattern of the gunship is now on the opposite side of the guns, i dont know how this happened. do you think you could take a look?

Alright, apparently you've already built an AC-130. Oh well, may as well rip the guns right off this and stick them in the cargo jet. wait, no. Bombs. Make it a B-52.

It looks like an AC130 :D
