Essentially you can fix the bug when cloning the Builder task to the end,
so you will have your Main Builder and a clone of it at the end of your project, you can leave the "Builder - Clone" Task inactive (Grayed out),
however the Fitness functions should be the same between the "Builder" +"Builder - Clone" you should keep this in mind while you change your fitness function/s.
