I have a ship I made and i used a QperfectionWeld on it just as I have with other ships before and usually when the game runs the ship is welded and unanchored and then it floats in roblox's terrain water under roblox physics. But for some reason with my one particular ship when i run the game the ship will say its unanchored and welded but yet it stays frozen as if i anchored it in place. if i move the ship in studio while running a server it will then start responding the way it should but i obviously cant do that in live servers for my game. What is going wrong that causes this?
