Rarely, the configuration saved in Canvas for module item placements of a Badgr badge within a course become corrupted. This is easily corrected by reinstalling the Badgr for Canvas app and reconfiguring the module badge placements. No data about your course configuration or badges awarded will be lost.
Reinstalling Badgr won't affect ongoing courses. When the app is re-added to a Canvas instance, existing configurations and badge assignments will automatically be re-established.
