Still no restore?

So… In a pretty stupid move I imported the wrong content files and essentially Hosed my project to the point where it was in-open-able.

It strikes me as strange that there is a Backup, but no way to restore?.. Or am I missing something? (which is entirely possible, I’m a 5 day noob right now).

Have a look at source control:
