Course and LearnTrack assignment to a voucher is now restricted by curriculum group. If a voucher is linked to a course or LearnTrack that you no longer have curriculum group access to, it will not show up on the list of vouchers. Therefore, if you no longer see the same vouchers in the Vouchers list that you used to see, then you may no longer have sufficient cohort curriculum group access.
Previously, achievements that appeared on a user's transcript may not have been properly displaying on the user's achievement record. A code fail-safe has been created to address this discrepancy.
