I’m at work right now but if you have a chance before is done with his thesis I’m pretty sure there was another user who was able to get two units to move at the same time (seperate paths for each unit) quite a few pages back. That user posted a few gifs showing his progress. If I get a chance when I’m off of work I’ll take a look and see if I can find it. I do remember this was after 's major refactoring he did of the tool kit so some info on how to do this should still be relevant.
