Running for 12hrs plus nonstop finally got the damn protea system. Now going for chassis. I must say this is certainly not right. There are only 5 items in rank3 loot table where protea parts assume 11.11% drop rate which can be said not little or big chance but it's illogical or impossible running over 50 rounds worst more and not hitting 1 jackpot. Be it rng or badluck but it's happening to many players. I truly believed something is wrong with the coding.
