Calendar/Activity completion issue

We have been looking at activity completion more closely since some new functionality depends on it - principally the course completion progress bar displayed on the Dashboard.

We have found that, for some third party plugins, the expected date for activity completion is not being added to the Calendar. The plugins affected are as follows:

Please be aware that if your course uses any of these activities, and also has course completion enabled, then any completion dates may not show up in your Calendar.

There is a workaround available for staff to force these dates into the Calendar which can be found in the Staff Moodle Help course.
