This is a mod that I have created, it adds three new chests that you can build for free. One chest will generate a random blueprint inside of it, another chest will copy any blueprint placed inside it, and the last chest will randomly mutate the blueprint placed inside it. I have not finalized the likelihood of mutation or of a tile getting an entity. I made this mod to be used with the recursive blueprints mod to build a fitness testing setup that you can use to evolve blueprints. Please not, that if you attempt to load a game that has not had this mod loaded it will most likely crash/not function correctly. I was only able to get the random generation to happen if I used on_init, so it MUST be a new save, I created a scenario that starts me with an infinity chest, and then use cheat mode to be able to build anything for testing the mod. please feel free to dig through my code and tell me just how terrible it is/ what I can do to make it better, at this point I am just proud of myself for getting it to even work!!!
