I'm attempting to play a "true" lone wolf assassin type. So I get to the lighthouse, position some barrels, make a big explosion, have the initiative and stealth. The turn after the Ghoul raises his dogs, he does something very unexpected: teleports to the trade ship in the harbor, slices up my butler--err, second character--and teleports back to the lighthouse. All the NPCs near the ship join the fight, but since the butler is dead, they just stand around.
I reloaded the fight, did the same things, same thing happened. Rather funny I think.
