Oh, I didn’t know anyone was still interested in this thread.
The issue is that my understanding of UE4 was too basic. It really is as simple as Casting the PlayerController -> AIController -> Move to Location.
I can’t remember back to what the issue I had with it was, it may have been that I wasn’t aware casts were context sensitive and so couldn’t find em 
Doing a lot better with it now, my game’s coming along better than I could have ever dreamed of thanks to UE4.
