Hey there @aleks_clover9! First I’d recommend getting acquainted with the AI debugging tools:
This will let you verify it’s actually going to the correct state and attempting it. This will also how your blackboard’s variables at all times to make sure that’s not the problem.
Now my first question would be to see if your MoveTo node’s details are setup to go to an actor or location. This changes how it works significantly, as if a location is inaccessible it will silently fail the event.
