Ah yes, someone else posted this problem, I made the necessary explanation. Normally the special scene is supposed to be the last scene. So those buttons that give an error should not be there. you are not missing anything as a scene. just don't click on those two boxes for now. If you clicked and got the error, you can continue by saying rollback, let me say it again for those who don't know. I will remove those boxes in the next update. Thank you...
