Error Message :

In some cases "Run At" exceptions are not executed.

It is not yet entirely clear which 
circumstances invoke the issue. Elements that may play a role are:
  • Rule of the Task is NEVER
  • Multiple "Run At" exceptions are added to the Task to run the Task for one-off executions
  • The "Run At" exceptions are recycled (an exception that has already run in the past is re-used for another execution in the future) 

OS: All
OS Version: N/A
Cause type:
Root Cause: Still being investigated.
Update to a fix version listed below or a newer version when available.

Fix Status: In Progress

Fix Version(s):
Dollar Universe 6.9.41 - Planned release 2018-10-01
Additional Information:
Workaround :
  • When the list of "Run At" exception becomes long delete old entries
  • When creating a "Run At" exception for a future run always create it by using the "Add" option, don't recycle
