It works fine, not sure what the past comments are talking about (one of them is missing the ChaosNPC dependency and got an error), it seems to work as intended. Plenty of options in the config, and the people complaining of there not being time to get time crates need to either just delete the loot from the ship and let it all spawn on the ice berg, or increase the sink timer to 10 minutes per stage. I got stuck inside the ship once it was fully sunk - the hull has an airpocket that stays while the ship rotates and sinks. Just let it sink fast and kill the npcs/chests onboard to remove incentive for players to go inside. I have 6 Heavies guarding 6 military crates on the ice berg and it's been fun seeing it ram ashore and explode several times over. Glad I took the risk despite several people saying it's dead.
