The game runs fine, but every child that's born has no traits. I don't get any error messages and tested if it wasn't just bad luck by making more children sped up. I'm not sure if its my mod list but this is what i have. I hope this helps

You are right, i did some more thorough testing with the relatives feature with Conquest Tweaks mod and i found the beginning slaves to have no inheritable traits. I didn't notice because they were the only slaves i kept for testing. I reinstalled the updated mod, and the trait bug is still there but i know it isn't your mod causing it now. Thank you for the help
