Harbinger of Ruin: Part 10 problem

Hello, i have an issue with this quest, i have killed several harbingers and completed all the empowered monolith plus kill boss + harbinger at 300+ corruption.
Yet it does not seem to update the quest and i can not progress.

is there a way to understand which monolith you have to clear and spawn the harbinger for the Harbingers of Ruin part 10? Why there is not a tracking system for these kind of quest? Can we have one please?

thank you

You should see exactly which Harbys you’ve done on Harby faction screen (Y on keyboard).

the heck man, that saved me, i had no clue that existed… THANK you
