Can Fairies have children with Spellcasters???

I’m very aware that there’s a pregnancy bug going around and I’m really hoping that’s the reason. However someone in my Facebook group mentioned that they couldn’t get their fairy pregnant with a Spellcaster, I mentioned the bug going around but they said that pregnancy works fine in their game. So I open my game and try to get my fairy pregnant with her Spellcaster boyfriend but after many tries she wasn’t getting pregnant. I checked MC Pregnancy to see if I could start a pregnancy there but her boyfriend wasn’t showing up. I checked to see if they could have a science baby and that was actually an option. The person in my Facebook group said that it’s because Fairies and Spellcasters hate each other but Werewolves and Vampires also hate each other but they can have a baby. If anyone can reassure me that Spellcasters and Fairies can indeed have children together or that they can’t that would be helpful.
