Last night I just logged in to play one run, and someone got a pink. So, i thought, just one more run, and someone else got a pink. I did 4 Nuri runs with different groups and someone got a pink in every run. I figured, this should be easy, it should be my turn soon. I played until 2:30 am and never saw another pink. Well, i was really tired at work and was falling asleep in a meeting. I stayed up late looking for drops, and never got anything.
