Was looking at this lady here and I noticed that her breeding history has extra "None"s in it although her foals are bravery tested lol

.

Same thing with this girl. Note, neither of the horses are mine, just something I noticed. I'm on an iPhone using Safari

It's been like that since Eve fixed a bug years ago where bravery ratings disappeared from the breeding history if the horse was AD rated after bravery rating. Guessing it's some sort of placeholder, so it's not really a bug, just not super cosmetic.
