I’ve tried adding that o my DefautEngine.ini and still no luck 
I’m still getting issue, its a rather odd one. I was trying to see if I could set up just on the AI controller, yet when I’ve removed the Behaviour tree from the ‘Spawn AIFrom Class’ node it has completely stopped the spawning of the pawn class pin too.
certainly wasn’t the case in 4.0.2 - Is part of a wider issue? I’m worried at point if there is something out of my control/knowledge preventing me from progressing here.
EDIT: I’ve now fixed the spawning and need assistance with the moving again. time no Behavior Tree. I have ran a print string from the player location I’m using, and there is a value there for the AI to go to. Really concerned that porting my project has broken something major within it. Desperate for feedback as soon as possible!
