 Version 1.0.7.4
  - Fix errors when using mods with bad HediffCompProperties.
+ - Induced ovulators will start with a lower number of eggs, but reasonably enough for a long breeding life. IUDs or sex with poor fertility partners may result in early menopause.
  - Updated max size areola images by wruf.
  - Title addition on pregnancy removed to match RJW 5.1.0.
  - Improve compatibility with RJW 5.1.0 for multiple wombs.
