Empty spaces in bonus tiers on rift

It took a lot of rifts for BHVR to fill in all the empty spaces on the free track but it was finally done and is definitely an improvement to the rift. Now there's several empty spaces on the premium track - tiers 74, 78, 80, and 84. On the last rift there was also some random empty spaces leading to tier 85 on the premium track. I get that since there are linked cosmetics it frees up those spaces but they should be filled with something if your not going to just move all the cosmetics down 4 tiers so the premium rift ends on tier 81 instead of 85. Maybe some iri shards or deep rift recolor of a couple of the other cosmetics that were on the premium rift. Just seems weird to randomly have those blank spots before tier 85.
