Idk, I'm not really familiar with how the mod works. Can you just ignore the second dragon, or maybe vore her just to get her out of the way?
The only fix might be to delete the mod, or delete the entire game and reinstall it. I'm guessing the save data is in the registry if you want to keep that, so you'll need to copy the values at HKEY_CURRENT_USER\SOFTWARE\Naelstrof\FuckBenneq
