bug in corrupting nexus blooming fields crowbell boss, no atlas points, cant progress atlas, help

Hello!

I had a problem in a map called Blooming Field, It was a corrupted nexus, the mission objective to progress the atlas, but the map was bugged and the boss could not die, the boss was the crowbell, it got stuck in the mechanic when runs and gets the giant bell, so it could not die because it not get damaged and it got stuck there not getting the bell and not progressing to the next stage.

So i lost the map completing it afterwards but now i cant progress the atlas, i dont find another corrupted nexus and i cant get points

Can you help please?

Thanks!
