legion drops bugged

so I just did a 4 way legion boss fight and killed every boss 8 times, reseting the center aura 7 times, and I literally got garbage drops and 0 timeless jewels. so how can I earn timeless jewels? are only certain plyers allowed for them to drop, do u need more ppl in your party? seems rigged

Got one last night on a 3way. First one I've ever attempted. All rng

27 - 2 ways
15 - 3 ways
9 - 4 ways
3 - 5 ways

0 - Timeless jewels

Most of the fights were me using ED to clear mobs while buddy focused bosses. Others were me just cyclone 120% movespeed kill everything. Best drop was 3 Ex shards... I make more currency just spamming t2 glacier with atlas blocking doing monolith only.

same bro and my zerker has over 1,000,000 dmg in the "in-game" tool tip page! literally 1 shot shper, and run thru every boss and all the minions during the fights aprx 8 to 10 times each boss! yet the drops are allways the same, a few incubators, some alchs, fuses, and jewelry div cards like the ones u get in the underground river
