First hit in Google so I aint starting a new topic on something already discussed.
Just had this issue pop up today on a daughters' birthday and also on the mothers' birthday, but not on the fathers' birthday. Resetsim won't solve it, however if you use NRaas's Master Controller mod and reset sim through that it fixes the issue. Not sure what the outcome will be later in the game though nor why the issue started in the first place but it might be because I was using NRaas's Autosaver mod and it could've been doing Save instead of Save As.
