Answering your 3 questions:
- I didnt even know there was a wiki XD Id have to replay that quest but dont remember it being that hard to find, sorry there
- Sorry to tell you Hope V is one of the only broken quests and cant be completed unless you cheatmenu or saveedit the variables
- I dont think all the breakthroughs are fully coded in but:
Depraved is unlocked after multiple Escort works
Loving is for completing your gladiator personal quest
Sadistic is also unlockable but for the life of me I cant remember if it's stat or quest related
