Zekvir's Influence stuck at 1/3

Doing a Tier 8 Nightfall Sanctum, killed all the empowered groups but Zekvir won’t disappear from the last one, so progress is stuck on 1/3.

Guess this means I’m missing out on rewards at the end of the run?

Just had this happen in Skittering Breach with the story active that has Nightfall cult present. My assumption is this is being caused by the Nightfall Initiate mobs that sometimes flee at 25% instead of letting you kill them.

So far my experience has been that if a runner is the final mob in a pack, it may eventually give you credit, but if they aren’t the last one, the pack bugs out and stays “incomplete”. I had it happen twice in this one actually, because after it happened on T8 I left and raised it to T9 so I could still get credit. No dice, apparently.
