Coran returns to Baldur's Gate while on Werewolf Island

[dscotton]

In BGEE 2.6 with the NPC project as the only mod I have installed - I've had Namara in my inventory for quite a while (did most of chapter 5 and Durlag's Tower). I got on Mendas's ship and get shipwrecked on Werewolf Island. Pretty much as soon as I walk into the village, Coran says he's going to find Brielbara and disappears. I assume this is a time based trigger because you spend >20 days on the ship, but how the heck is he going to get back to Baldur's Gate from the island? It seems like this trigger should be disabled while you're there.
