Ok here's the way to save overloading. Make a floating platform outside the map so people can't jump on it. Make a big pile of weapons and equipment that you know you aren't gonna use on the platform. Make sure its all close together. Then when you think you have enough, put a crate in the pile. If it dissapears then just keep putting moveable objects (Crates, Fusion Coils and Power Cores). If not keep adding weapons and equipment. Once you think you made a big enough pile start a new round. If you did everything just right and you made a big enough pile, the map will be overloaded, even if you save changes and end it the man cannons will still be gone
