Atlas Progression Blocked? Cant find more Corrupted Maps. Level 93

Pretty simply, I am level 93. I have played every season past level 95 and I always explore far on my atlas.

This season I am having an issue. I am not able to find another corrupted nexus. I have done about 15-20+ towers since my last nexus. This seems like a bug or that they are spawning far too few and in between.

I cannot progress my atlas boss tree and thus cannot get to the node to increase the level of maps that have a boss which puts me at an extreme disadvantage for finding items since I cant easily make tier15 maps level 81

Maybe they should spawn more initially and then less often later so people cant abuse the mechanic to get level 83 maps all the time??

or something to make it so its faster to complete the atlas tree but not abused by people farming later
