Fallen From Grace Quest, ACT 6 - Does not complete. Run over 20 times.

I have run the Fallen From Grace quest to clear the twilight strand and have tried multiple times - at least 20. I have tried many variations to my attempted clear. Not using a minion/golem, not placing totems, not placing mines, and doing my absolute best to not kill anything offscreen by positioning myself so as not to fire in an open direction (this is very tedious). I still cannot get the quest to complete. I have had 0 (zero) remaining on every one of my attempts. I have not experienced any indicator that says additional remaining but the zone was empty.

I really would like to be able to have lily as a vendor in my hideout, especially for any new builds I play. Without completing this quest, it is impossible for me to have this available. I would really appreciate a viable solution to this problem, whether that means fixing the bug, which is apparently very common, remove the quest and just let players invite her straight away, OR complete the quest for my account. Take your pick, please.

I am new to POE and I got started in POE2, which stoked my interest to play POE. I would love to be able to experiment with other builds and have this option available to me. Thank you.

I have the same problem, I can't finish quest
