When taking a boat from any of the two docks CG or MC, with the destination in Midgard, players on board the boat will be bug dropped at the same location every time.
They will be considered to be riding the boat, but cannot manually disembark, they swim in the water near EV where they are dropped and can move around, but they cannot attack any guards (we tried).
Once the boat reaches the final destination the player is teleported there.
EDIT: Boats from nGed ware fine, only MC and CG boat routes are bugged.
