gunner AI in M4 scorcher will complain "cannot fire, adjust coordinates" is player is also in the tank (doesnt matter what position), upon executing doArtilleryFire command. Double checking the fire condition with inRangeOfArtillery returns true.
If player gets out of the tank AI fires no problem.
Create m4 scorcher tank and put ai in gunner seat
order it to fire to position in range with doArtilleryFire
If everything goes well, get in the tank yourself and order AI to fire again
AI complains of the wrong coordinates.
Also it is possible that AI will not complain at all just wouldnt fire until player exits the tank.
I've had very strange experiences with this command in general, in one of my missions it works perfectly almost every time and in another they always move their gun and move it back without firing. However I'm not too sure what to report as I can't get consistent results.
Voted up as I can actually reproduce this consistently.
