Was just in a brig and had a sloop attack and kill us. The suspect thing however was he was able to take two entire blunerbus shots and multiple sabre hits., Was able to fire cannon balls nonstop, with perfect accuracy to hit the cannons the moment someone got on them, or perfect hits on masts. He also was fired about 10 chainshots nonstop in a row as well, fully ignored his ship being on fire, and then spammed "Everything is ok" after he sunk us.
This was all on Xbox as well.
He was the solo person on the ship, and my crewmates also found it highly suspicious.
