I've counted my runs, I am currently on 87 and I have gotten 1 night aspect bp, 4 day aspect bp, 19 night system bp, 11 day system bp, 14 night neuroptics, 5 day neuroptics, 2 day chassis,and 0 NIGHT CHASSIS, if I dont get one by 100 runs I will deem it impossible to get night chassis and that DE should change these BS drops rates.
