So far there is no need for any other hotfixes or patches. v0.15 appears to work as perfectly as possible at the moment.
I mean, the repeatable anal ending in slutty schoolgirl outfit for Ash are switched: cum inside means cumming outside and the other way around, for example. But that's a small mistake, the content is there, so no worries or need to patch, but you should check that on 0.16
Plus, I think some of the events come too soon if you start over. For example, I went trough Kate's story without solving any riddle, and yet we talked about that she is the riddle girl. Or I had the Juilet-Kate-Ashley sleepover after Asley, Feicity and Emma were unsuspended, and Ash talks about how much Felicity changed, and that's not happened at all yet, because I didn't built the second floor for a long time... or Ellen talking about me like a son to her in Maria's storyline, and yet, we have sex with each other regularly.
I know it's a sandbox porn game (a really good quality one), but it's more than that because of the story. Maybe you should make these restrictions optional, for example "truestory" maybe should do more than changing clones to twins, it sould make the story more strict with the events. I mean, there are a lot of occasions, when you get the message to do something before you can go further with the story, but it's more room for this. And I think it's easier than alter the interactions in these situations, but os course that's a solution too. But in this state, it's off sometimes...
