Do I need to have any specifc stats, or go at a specific day/time? None of the available NPCs in the entire town have something. Going by Raine's gallery there should be another main quest though. (The thieves to catch were in the slums, in case there is a second thief quest) I should be on 0.13a
Edit: Apparently, I continued an older save file, and the quest got stuck. It worked in a new safe file.
