I'm currently playing 8 versions of the game, all at different stages.Datapoint: someone on the discord couldn't get Frida to give birth after Garden & Waystones II were done & 20+ days, without giving Balder to Mia yet. They did rescue Mia earlier, dunno if ignoring her completely skips giving her Balder as a requirement.
In the latest, Liandra has disappeared, as expected, but without completing the stable girls date nor the "get past granny" quest.
In another version Liandra refused to disappear until all those quests were completed and in yet another she refused to disappear until days after the quests were completed.
There does seem to be a great deal of variation in the game depending on the route you take.
