Shores of gold revenge

So we are on a full gallion at the shore of gold inside the temple fighting the final boss. And we keep hearing canon fire. Well there is another crew at the island. We finished the boss got the skull and found out the other crew sunk our ship. Invited them to our party and asked why did you sink our ship? And his response was “it’s a pirate game!” Fair enough. So we snuck on their ship and found out they had the final medallion to get into the temple so we took it when they weren’t looking and sailed away. Guy from the other ship messaged me said give me back the medallion. I wrote back and said “ it’s a pirate game. Then sent a picture of us standing behind the medallion at the outpost to him after we sold our skull
