In the BT show in the image, its seen that the Decorator even though failed it still allowed the continuation of the branch. Unless I’m wrong, once the “search Enemy” Service sets the Enemy blackboard variable, the decorator should be notified and abort self branch.
This issue however only happens in the first couple of seconds wen the actor is spawned, after that, If the actor finds an enemy on its way to the Destination it works as expected. I’m using 4.6.1 version.
