picking up pigments bugged

[Ragingwasabi]

during tridolon fights, picking up the black shard pigments is buggy. i have both drop chance and drop booster and it  generally seems to give me 40 pigments from a single drop. 

but not always. sometimes it gives me 10. sometimes nothing. so basically i walk over the pigments and it disappears, nothing is picked up... sometimes it shows 50. presumaby from picking up a 10 and a 40. its so random.

i have suspicion it has something to do with operator and warframe transitions.
