(don't click the green flag. you won't like it) If you are a Scratcher or New Scratcher, don't put these two scripts in your project. You wish you haven't. I am here to teach you that this old 2014ish trick isn't good. who knew clones were so laggy? If you are a Scratch Team member, please fix this old glitch. It is so easy to make this mistake and causes massive inconvenience.
This is an old trick, when cloning was new, we just needed two tiny scripts, and it would create lag. I guess it still works. What happens? When you click the green flag, the browser becomes an unresponsive app in your computer. Things lag, and refreshing the page seems to be worse. Just close the tab and re-open scratch. Sorry for any inconvenience tho.
