Hi, your AI perception image above shows 3 configs. OnTargetPerceptionUpdated will fire per sense, so even if the target is plain in sight if e. g. some hearing stimulus reached its age limit it will fire an update with SuccessfullySensed being false also even if there are other still active hearing stimuli for that actor. Don’t know whether that is your problems, but from just checking SuccessfullySensed you can’t make any assumptions about the actor being in sight of the AI or not.
Also you set max age to 0, maybe try a value greater than 0.
