I figured it out. Somehow, in the Prefs, "Monster Sex" got set to Disabled. NO idea how that happened, not a setting I ever would have changed. If anyone else has this issue, click on Prefs at the bottom.
Thank you. If possible, please post your save where this error occurred (it might be helpful for the game author to look into this issue). You will be able to delete your link or messages after my reaction to it.
