I'm sure it's probably been said already, but the incest patch needs to be updated. Right from the beginning it isn't working properly when the Mom is telling the MC about his Dad and refers to him as "Eugene" when it should be "your Dad". This happens a lot, like when Allison asks him "Do you remember Dr Donovan's main research?", when it should read, "Do you remember your Dad's research?". The MC also repeatedly refers to his Mom by her first name.
Also, from what I recall of the game before it had to get patched, Olivia and Daisy are his biological sisters, they were just all given this "supergene" when they were conceived. So the lines about them not being so shouldn't be in the incest patch.
Hoping someone can update the patch to make it work for the new version.
I just wish they hadn't uploaded the rpyc, since it's harder to decompile something that's not native to the game, since you can't do it with UnRen. If they had uploaded the RPY, at least I could look and see what's wrong with the patch, if anything.
But I honestly think it's partially the script's fault, with mislabeled tags so the patch doesn't know to replace it there.
Like the example you gave. The patch is set to call certain Eugene Tags "Dad" instead of "Eugene", but if the Dev didn't use the right tag, then the MC will call him Eugene and the patch won't affect it at all.
If you want, you can actually go in and change the tags yourself in the script file. The Dev left clues (which are wrong for Daisy), as to how to change them.
Edit: I actually checked the script for the Eugene call, it was hard typed into the code. So that's a flub on the Dev's side.
