Where are the "Corrupted Nexus"?

To finish the quest in endgame I have to complete "Corrupted Nexus".

The first 3 were easy to find and close to the starting point....took me 6-8 waypoints to finish each one.

But after that I can't find even one anymore....I'm surely already 30 maps in, cleared 8 towers in the "fog of war" and not even 1 Corrupted Nexus.

And that already in T4....11 more to go. :/

Seems something went wrong here becasue this is very frustrating if I have to fight all my way to the next tower, doing many huuge maps with 0 content in it (becasue Tablets are also very limited and you don't want to waste them on every tower on the way) .....only to end up at the next tower without corruption.

Plus I didn't even start to farm and I've already lost the overview in my map, becasue the only thing I can do is to go straight to the next tower to hopefully find a corrupted nexus so I can complete the quest.

Is there a bug atm, that Corrupted NExus don't appear at some point because it seems so?!

PS: I personaly liked the old quests more (finish 10 maps of T1-15) becasue this way we player had the possibility to play the content we want instead of being forced to rush from tower to tower and hope to find a corrupted nexus 40 maps away in each direction.

Corrupted NExus Quest could be used as special reward or have it's own tree but being a must to complete the main quest and unlock the main passive tree feels not that great.

It feels like a way worse version of the old Last Epoch monolith system and it has been reworked now for a good reason. ;)

Bump, problem still there...no Corrupted Nexus available, no matter what direction.

100 maps in and still no corrupted NExus...still T4 quest.
