I haven't read through all the comments so im not sure if this question has been answered, but for whatever reason I'm having issues with AI turrets. The turret is able to lock onto the target, but for whatever reason, it deselects the weapon. When it tracks the target and manages to keep the weapon selected, the turret will follow the target but not fire. Sorry if I am being to vague, but if you need any more information, please let me know :D
