    The coordinates for the the mortars are not correct. The plans gave me Aqulia’s Wheel, not the mortars. Does anyone have a correction or is it my game that the coordinates(630,660) are not for Mortars

    For all the guys who complained about not finding the right treasure, the game literally tells you what you’re going to get from the treasure chest the map leads you to right up above the map. Just letting you know that there’s a quick way to validate these incredibly helpful tips (unless they’re wrong, then it’s not so helpful :P).

    So, you cannot collect this without an oline subscription and doing the fleet missions? This iritates me greatly. I dont wanna finish the game with ship upgrades at 96 percent :c
