PoE2 Venom Draught Slithering Dead quest bug

Says quest is done. It's not I did not choose a reward, don't recall giving option to choose reward.
Map if you hover over the icon shows rewards you choose, normal shows my reward, cruel shows no reward, shows it as haven't completed.

Possibly someone took my vial before some patch a long time ago? This was done long time ago.

Anyways I want my 10% chaos resistance.
Here is the video I took to show.

I need CUSTOMER SUPPORT, I'm not here to do bugs. I need my character fixed. I've already emailed support@grindinggear.com I have not got a response. This email was 2 weeks ago.

This happened to me too. Everyone is saying waypoint to a (present) area and then make your way back to ziggurat, but that doesn’t work. Everytime I enter ziggurat it generates the (past) version. My other character has the completion on this because I chose a draught. This character whose in end game does not.

Is there a way to complete this side quest after endgame? Or did I miss it, and now my monk is forever -10% chaos res

same problem
Please fix that!
