In some circumstances curricula fail to complete as expected

We have identified an issue where in some circumstances, curricula configured with a pass mark may not complete as expected. 

This issue does not apply to curricula that do not have a pass mark, and may not apply in all cases where a pass mark is defined. 

Our developers have identified the cause of this issue and a fix is currently being tested. After the fix is deployed, an update will be made to correct any data which is incorrect as result of this issue. This issue is limited to the calculation of the completion state for a curriculum, and does not effect the underlying data used to perform that calculation, as a result, after the fix is deployed the state of the system will be as expected, and no data loss has been identified as a result of this.
