A command prompter OS I've been working on. Almost got it, then I found a bug that can't be fixed, or atleast not by me. There's a list of known commands, meant to be analyzed when you enter one. After startup, if you try to enter pretty much any command, there's an 8/10 chance it will tell you the system crashed. This is because after the command is not recognized the first time, it is sent to be checked again. If it is recognized, it just shuts down. How would I fix this without overcomplicating? Remixer: Your problem was the list. I also added a few new functions.
