Can you finally fix the Survivor objective in the Revolt Against the Consulate event?

Machine

Event: Revolt Against the Consulate
Encounter: Heroic Intervention (the fifth encounter of this event)
Objective: Survivor (Win the fight with 20 or less HP remaining)

I always play this encounter with Ob Nixilis, Reignited, so it's pretty easy to control how much damage you take to finish the encounter with 20 or less health. However, during the event ending screen, the one where the objectives are checked, Ob's HP jump from less than 20 to somewhere in the 40ish, causing the objective to be lost. This means that an additional encounter has to be played if you want to reach the last progression reward, which means lost time.

Can you please finally fix this?? This time around I didn't use any life gaining abilities, as it is thought by a major part of the community that this may cause the above mentioned issue, which is obviously not the case.
