so I have a ship and it has 3 harpooned condition cards assigned to it. It then suffers 1 crit from an attack. do the condition cards stack dealing 3 damage to all ships at range one and dealing 3 damage cards to the ship then remove all three harpoons. or does only 1 at a time trigger dealing 1 damage to all ships at range 1 and 1 facedown damage card to ship, removing 1 of the condition cards and leaving the other 2.

They all trigger... No reason the other two would not trigger.
