I think the crackfix solves most of the problems; at least, I haven't encountered any.
About the actual expansion tho, meh, I get that's only a part one tho. For all it's worth, imho Hannah was overhyped and I think she's going to be featured in one of LOP's next games, and they're essentially using LwT (their most popular IP) as a launchpad for that; for how much she was hyped about she only has a few scenes, and it seems to me that Leonizer (the writer) really, really did not want her in the story. Whenever there's an event with Hannah you get the chance to shame her, essentially, and distance yourself from having sex with her (which kinda defeats the point of having her there in the first place tho); for her scenes, you essentially have to please her as much as possible and be a total yes-man, and right after her first full-penetration scene after she tells you she's leaving the game... And that's that. No repeatable, nothing.
Heck, if you want the early scene with her it leads to her leaving the game right after. It seems as if Leonizer really wanted to write as little as possible to meet the quota of sexy images and then be done with her. The fact that she's essentially a temporary character also kinda defeats the purpose of having relationship points with her to begin with, since it's all about picking the right answers only in her events anyway.
With how much her dialogue foreshadows her "next project", it really seems like she's there to basically just promote a future game with her in it. I don't know, it makes sense I guess, but it could've been executed better. It's kinda skewy.
