 Version 1.0.6.6
- - The menstruation cycle used to start ticking exactly one game hour after loading the save. Now the hour timing is consistent across a save/load.
- - Every womb will tick at a different (but consistent) time after the hour per pawn.
+ - The womb tick timing is now more consistent across a save and load, and also spread out across pawns.
+ - Fix error when an egg fertilized by a nonexistent/garbage collected pawn (e.g. in an NPC's womb) tries to implant.
 
 Version 1.0.6.5
  - Handle climacteric induced ovulators a bit better.
