Instead of using the Get Random Reachable node from the Get Actor Location from the player try just using the location of the player and set your Acceptance Radius to include the 20 from the Random Reachable node. The AI may be getting no return results that are within 20 and so it returns failed…20 centimeters is an awfully small point for him to try to reach and fit in.
I’ve been stuck on this for HOURS and couldn’t find a single answer to this - just a bunch of people with the same problem, lol. Hopefully anyone else in need finds this.
