Was wondering if anyone else has had trouble getting this Scroll for the Achievement? Everyone I looked says it's available during Stage 5 (Just hit it this morning). Been camping the Docks all day and the ship hasn't spawned. I ran to the Swollen Vaults and was waiting for Molthor to spawn and at one point I saw the ship, I start to run to it and it phased out. Ran back to the door and saw it, but even camping that same spot it still hasn't popped.
So was wondering if anyone has had any luck getting this and any tips they may have.
