Proof Fragements not dropping

[NaysWindu]

EDIT:Fix for those that might see this, and don't comment. I found that by going into solo play, the drop rate increased dramatically. Might work for you. good luck
Hi there

I'm trying to do the mission "Limbo theorem", and after doing multiple rounds of the archwing mission, I have only gotten 1 Proof fragement (which was halfway through the second round of 3)

Am I doing something wrong?

Here is the most recent round

Aren't the enemies supposed to drop it?I would think that at least one would, after killing 43 of them

I even have the drop booster active from my daily.
