canonical in the game world the three ash's do not exist in the same universe. Besides the computer that is more an in game cheat there is no way for one to become the other. If you are with female ash is and always was female, and so on.
People are complaining that the wife took actions in non-female ash route, and it reflects on female ash's route. Technically as they're two different paths that while similar do not intersect they should not be conflated.
On one side you are the only one with a dick on the island have been, and will be. On the other one you are not but you want this to happen. You make this happen, and while people are complaining about how easily she allowed it. How easily are people talked into even the most absurd things especially in the heat of the moment.
If reading about it in the forms is the issue stop reading the forms. If you play your game with your preferd setting you would never even know. As far as I have seen most people are happy as long as they can avoid it/ it never happened in there playthrough, and that is how it is
Question for curiosity sake
Alorth if she gets pregnant with ash's baby, and you make ash female will that brake the game, or just make the story nonsensical. If it does work with how some things are exclusive to certain ash routs won't that make issues later on. Like if ash gets pregnant. Technically ash's kid with the MC, and ash's kid with the wife should not be able to exist at the same time. As only one ash can get her pregnant, and that ash can not get pregnant.
