If you use Hidden Cove to fling a ship to a Mysterious Island, can you immediately roll for that Island’s effects? If you can, can the target ship be given a move action to move away, re-dock and roll for effects again?
Hidden Cove docks the ship, so you do have to roll for the island effect immediately. If you used your action(s) to move and redock at the same island during that same turn, you have to roll again, possibly getting additional or doubled-up effects.
