I am not sure exactly what is going on, but while I have gotten the scenes for the character to be impregnated, including while the character had Heat and also the cybernetic vagina that boosts fertility, i cannot get the pregnancy to actually occur. I don't know whether it's an issue with the synthetic womb, Sera, or the character. Stat logs all look normal, actually Correction, was checking other logs and in the encounters log it still lists Sera as infertile, which might be linked to the issue. I also went and got a random pregnancy, Amber because she was there to be specific, so it isn't a character specific bug on that end at least. I played the priapin scene at least five times, mostly with 1000% fertility modifier from heat+cybervag, and a couple with a 500% from just heat, without results.
