Sort of unrelated, but those images in your screenshot should be translated. You need to run GameUpdate.bat to grab the latest update from Dazed's repository.View attachment 4435479
I definitely feel like it's coded so that you can't get Merumeia pregnant from the prisoners if Reiri is already pregnant (I got her pregnant before entering the prison). This is a big shame because I wanted to get her pregnant on a random prisoner instead of the guard.
This will also fix bugs, but I have yet to play the game myself, so I'm not sure if what you're talking about is a bug or not.
