In the documentation I can see that, to restore a course I can:
Go to Site administration > Front page settings > Restore (if you have front page permissions) or Administration > Course administration > Restore (if you have an empty course to restore into.)
Not on my absolutely pristine, out of the box, vanilla installation of Moodle 3.3+ I cannot.
Is this a documentation error or me being dim (again)?
When I restore by other methods I can only restore into a new course too.
