Here's how to recover archived content:
Go to Settings > Archive

When you archive a Course, Resource, or Check-in that's part of a Module(s):
It will be removed from any Module(s) its part of.
Trainees that completed that Course or Check-in will still see it as part of their completed assignments.
If the assigned Course, Resource, or Check-in has been assigned but is incomplete, the assigned Course, Resource, or Check-in will be removed from their assignments.
