Ok this is what I have made.
1 Second into the game we spawn the counter with the scene component.
2 Seconds later the blackboard communicates to the character to walk to the counter.
This is simply me setting the blackboard value.
This is the end result!
It seems to work fine for me 
So what you are saying is that when you spawn a counter then the “MOVETO” node doesn’t work if the counter is spawned at runtime…? Did I replicate it good enough?
