The reason you guys are getting different experiences is because there are multiple sections of code that have close to the same dialogue, which one you land on depends on what you've done previously. i.e. If one of you completed all of the sister's stuff, but the other hasn't, Aunt Diane's or the Mom's dialogue may be different even if you're both at the same scene.
Thanks for posting these, some I'd already fixed but not released yet(because I was waiting for exactly what you folks are doing now, giving me more stuff to fix).
Some of the bugs I'm honestly waiting until v0.18 to fix, because I intend to do a more comprehensive override of dialogue, including restoring the original incest content. I don't want to do that prior to Jenny's code being re-worked though. This would include lines like "Aunt Diane?" because the original line is just "Diane?", something multiple characters say. When you override the dialogue the way I did, it replaces that one change for all of them. This is the easy way of doing it(but not even remotely the best), I just wanted to get something out for folks who'd been waiting for so long for a patch.
BUT, again, thank you for taking the time to post these. I plan on releasing an update at the end of the week with changes for this stuff.
