I snuck onboard a galleon last night and stole a haul right from the captains cabin, totally unnoticed including a chest of legends.
As they were sailing i loaded it all onto their rowboat, rowed to the nearest island (crooks hollow) and got the mermaid back to pick the rowboat up.
Only the server merged!
In future i know that im never risking that again. I'll row to the next outpost instead.
