Hey, I’m sorry that I keep posting these topics - if I could delete the other two obsolete ones, I would, but I can’t. 
Anyway, my latest issue with getting the AI movement system detailed in the Getting Started tutorial is that while the line to a new waypoint is drawn, it gets stuck when it has to navigate into walls, as if it were ignoring the path and just ramming into the wall constantly. I still have the issue where using the default SimpleMove instead of Move will either crash Unity or just make the AI rocket downwards.
