@xultanis-dragon I'm not 100% on this but way back in the day my galleon was contesting shark fin camp. We sank and while three of us were sailing back to the cloud, our fourth member stole the other galleon and sailed it off. Then the kraken attacked it. We watched the kraken battle their ship as we came back to the fort. Now my thought is, if the fort was completed, they wouldn't have been on the island allowing their ship to be stolen. They would have killed my crewmate and defended the key in their ship. If they had the key on the island, they wouldn't have been able to return to their ship to fight the kraken and ultimately saving it to come back. If three went back and left one guy with the key, they would have easily lost it to our crew and I don't believe they were that dumb.
I genuinely feel the fort was still active when the kraken hit. That's why we left their ship to its fate and went back to the fort. This was before everything that had been added. So I believe in early builds, forts and krakens could exist at the same time.
Many people argue the mechanics now saying that they can exist at the same time and that they have witnessed it, but I just believe they are recalling previous builds when it happened and possibly as early as cursed sails or even as late as shrouded spoils changed that.
