I've been doing NMDs from t30-t60. I got my first 9 to drop, did the boss, now they aren't dropping. Is this a bug?

Update: I've got some more to drop. Just not 1:1. I got 9/9 when i started doing t30+.

Yeah it seems they go straight to ur consumables tab, i dont think it shows as earned reward?

I haven't seen one on the ground, in the completetion window. They just pop in your consumables tab like you said I think.
