Strange, this should have been fixed by the overwrite-fix PR, I'll take a look at it

Ah its because this is an assessment so it does not auto sync to the backend db. What we need to implement is a Save message that is sent to the webview whenever the user saves on the vscode editor. As we discussed in a previous meeting, if the user exits VSCode without saving, neither should we save the code on Source Academy
