I have another bug, I stuck here where you choose a whore(northern warrior), cannot leave the scene or proceed further
I can read that you're playing 0.14.c?.... it is hard to read, but looks like it.
Thing is, those problems were supposed to be fixed. (There was a big hunt to chase down those bugs back 3-4 months ago, and since then no one reported them...) So I'm checking myself those scenes that you say.
1. There is one option bugged in the Cooper girls show; The "Not now" one; (So thx to heading me in that direction).
The others ones work. Thanks for reporting.
PS: But the northern girl option should work. Anyway now is fixed for next release.
2. I checked the Kithra&Klow scene, it works for me, at least without using speed modes. It should work... Unless I fixed the bug after 0.14.c release but I'm not sure about that at all.
Conclusion: I don't know why your getting a bug choosing northern warriror or in the k&k scene if you're playing last release. Have you tried a pair of times and always get them? Are you using speed modes just on those moments?
