Does this happen to anyone else's games? Notice how this G1 game-bred dam was bred back to her FATHER?! This is not the first time SO7 has given me this either - raced a horse against a monstrous undefeated colt once whose parents were siblings. Gotta wonder how someone missed this building the "realistic breeding" model, there's no way that this amount of incest is real or sustainable.

How many seasons have you completed in that save?
