I having exactly the same issue here. Waited untill im done with almost anything esle before doing the new stuff and got locked out of her content it seams.Hey everyone, I've come back again for your help. I don't know if it's a bug, if I have to wait, or if I'm doing something wrong. It's about Dr. Frost (I think that's her name, sorry if I'm wrong). The dialogue options for the tests, like the modifications she can give you, such as the futanari one and all that stuff used for Anna, aren't appearing anymore. I shared a route with that weird specimen that looks like a floating jellyfish, and the doctor got pregnant. Some time later, I went back, and she gave birth. She told me that the specimen (I have no idea what it's called) was taken to labs outside the city, and the dialogue options she gives me don't lead anywhere. If I go back another day, she says the same thing and gives me the same dialogue options, and none of them are for giving the samples, which are the vampire blood and the divine tear. Oh, another thing, I don't know if it's relevant, but I haven't freed the guy she has locked up yet.
Also, for some reason there is no cow prints for Katerine and Emma at the far anymore
