The new guide is kinda unclear sometimes. It says that maincoone Rhianna requires the romantic advice talk with her, but what it doesn't say is that you need to tell her yes when she asks if you'll become a poodalist to actually unlock. I said no and was confused when it wouldn't let me tf her.
Also, maybe you should have a section in the guide for missable things and also maybe a section for sex scenes? The Rhianna one, for instance, is there if you do the love at first sight tf, but I dunno if that's the only way to have it.
If it is, maybe you could implement another way to get the "Charmed" attitude than that limited time TF, maybe something like offering a similar TF if you've flirted with her, or maybe if you've gotten to the romantic advice talk?
