Who is the impregnate event with? You + slave? Slave in the kennels/prostitution?

No, just aric, I even disabled the constant mod from maverik and the error continue to appear. And it is happening on all slaves as well. Whenever I have a slave or multiple slave having cum in womb and is ovulating at the same time, this error appears.
The problem is I have had this working before, but just after a new save this function broke. I even reinstalled the game and the mod again and again, but it just won't work for me.
Looks like this issue(https://itch.io/post/1742260), a bug in the code. Edit: Effects mainly prostitution and sex with animals.
