Can't Progress Cataclysm's Wake Atlas Quest

the fact that even is a question is wild.

My cataclsm's wake states "discover the radiating source of corruption" in the map ive completed. This is nowhere to be found ive spend over an hour wandering around the empty map and theres nothing here. When I leave the map the quest state from my hideout states "travel to the corrupted nexus". The corrupted nexus map is complete and my atlas shows cleansed areas around it. All the surrounding corruption has been removed. I still have zero atlas points. Have I done something wrong or is this a bug?

Same here.. I think its a bug hope they fix it asap..

Go to the map with Corrupted Nexus mod (It has icon in atlat - It's only can open by using a map has more than 4 mods). Complete it by active all Stone Altar around map to open middle area, kill middle boss then kill Corrupted Boss (it's was spawn after middle boss defeated).

So if we completed these improperly, and just finished the map, the corrupted nexus then goes away, is there a limited number of these? are we out atlas points permanently now? I think the quest wording needs a rework.

Has this been resolved yet or is GGG atleast aware of this issue. I'm just hard locked behind this now

i cleared ~ 10times tier1 map and did not completed cataclysm's wake quest to unlock atlas

Similar issue. In my case, I entered the Corrupted Nexus Map, which had a Map Boss and Delirium Mirror as its mechanics. Cleared the Mirror and about 2/3 of the map, then died to the map boss (not realizing that would despawn everything else on the map). Respawned and killed the map boss, completing the map and converting the surrounding areas on the Atlas to Cleansed areas, but not progressing the quest. The rest of the map is empty, and as with OP, my objectives are "discover the radiating source of corruption" inside the map and "travel to the corrupted nexus" outside it. I used a t2 waystone with 4 mods. I have the quest to discover a precursor tower pending, but have not yet run one or used tablets, in case that's relevant.

Same experience here.
Really frustrating

It worked for me, dont know how but last time i put t15 map the corrupted boss spawned and mission were done!
