Mission Architect / AE NPC "activation" radius is 150 ft. through walls

[Kartanian]

NPC activation distance. Having a character 150 ft away, through multiple walls, activates NPCs. It also "counts" in the AE system for mission objectives as "bring Person A to Person B" and prematurely finishes the mission. Consistent across maps and for a number of years. Known issue. But no remedy available to AE arc writers, yet. I would LOVE to have activation distance equal regular NPC aggro range as a remedy. (Not really a bug; working as coded intended, but ends up being a bug to what we can do with the toolkit.)
