Delirium Closing Early When Flicker Striking through Map (Bug Report ID: #3416594799)

When flicker striking through a delirium map, I was killing many mobs and rapidly going through the map, but it did not extend the timer at all. It ended on only 2 delirium drops almost immediately. This is about the second or third time this has happened, with it mainly happening on linear maps with lots of packs, such as Hive.
