The quest ‘Next To Godliness’ is completely broken for me. I’ve tried everything and there is simply no way for me to progress it. I go to the bath house in the evening to meet Hans — if I arrive anytime before 9pm he tells me I’m too early and to come back later, but if I arrive even a split second after 9pm he immediately leaves, gets on his horse and rides away to his bed. He then remains in his undergarments from that point onwards and you cannot talk to him anymore, even days later. I’ve tried every way imaginable to get the quest to trigger correctly (seriously, I spent about 1.5 hrs trying different things) but it simply won’t work. He never gets into the bath and the scene never triggers, he just leaves at 9pm every single time.
I’ve resorted to going back to a previous save before I ever even triggered the quest in the first place as a precaution (I lost a few hours of game time in the process). I was concerned that if I moved forward in my game with that quest bugged as it is, not only would I never be able to complete that quest but it might also lead to even more problems with future quests that involve Hans (since it seems to break his behaviour in general).
I should also mention that I’m on PC and I started the game on the current patch (1.4.3), so this isn’t an issue caused by bugs from earlier versions.
