So I have my scripts in serverscriptservice and everything's working fine but the whenever I press start the script just went missing.
ServerScriptService Is a Server-side handler, when pressing
Play, you automatically run as a Client. Client’s don’t have access to this handler, much like a ServerScript doesn’t have access to any Client-side handlers, this is why you cannot see anything. ROBLOX added a button that allows you to switch between Server and Client, click it to switch and you should then see all of your Scripts.
