Does not matter if it's (90) or (5) or just EscapeArea(). The NPC's immediately disappear.
Some NPC's however do wander away although they literally have the same Action as the one I just modified (Alec from Romantic Encounter in Candle Keep walks away, Aoln the Ranger in the Coast Way immediately disappears [both have EscapeArea()]).
There are also no other EscapeAreas in the NPC's scripts which might conflict with the EscapeAreaDestroy() action in the modified dialogue of the NPC.
Also, the area where the npc's located has exit points.
