How to allow NPC to attack Sentries/Turrets?

I originally started with a Guard Spawner, but realized the guards wouldn’t attack the automatic turrets, even when the turrets would attack them, in range, etc…
(These were non-hired guards)

I then set up an NPC with custom verse behavior, in hopes that if it had the guard class, I could get it to use the ForceAttackTarget method. But since it’s coming from an NPC spawner, this seems to not be an option.

Does anyone know of a work-around? Am I missing something?
Thank you.
