sorry you all but it just occurred to me that I broke the single unit ship AI with versions 19 and 20. It just hit me while onsite at one of my customer's where the problem is. I'll make the change tonight when I'm back in my hotel room and then someone will have to test it for me because my company laptop is crap and can't run diddly squat for games (I think they did that on purpose!). It's a simple fix also but easily overlooked during testing as I tested convoys only
