The issue has been addressed in Argent Advanced Technology 5.1A-1804-B

Technical Background

The issue is caused by coding error

Internal Event has an internal time stamp for delayed Events

The timestamp is the time that the Event should be fired if the condition has not been corrected

The Engine mistakenly replaces existing internal Event of offline Daughter Engine with new ones without keeping the timestamp value

As a result, the Event is kept pushing to the future to fire

In some combination, the Event might not be fired at all

When the condition is corrected, the event is simply discarded as transient Event

Resolution

Upgrade to Argent Advanced Technology 5.1A-1804-B or above

For customers who cannot upgrade immediately, consider resetting the Event delay seconds to zero
