Drips - "and you hear groans from below", explore the ruins below; not working

[Oskar Maxon]

Tried taking this quest today. Quest placeable says Party size 1-5, lvls 2-5, this was with a single lvl 5 pc (Karrak Gherbast, account Oskar Maxon).
Was able to take the quest, got quest invite tool and update in bombat log, however when trying to enter the area I get the messege: "[EFU Quest area]You decide against entering without more preparation of company".

Updating quest by "adding>" other members either by quest token or by placeable did not solve this.

I think I know what this is and will fix for next reset.
