If you completed rescuing Dakota months a go and your using an old save from then the first version of that quest was set that if you missed the birthday party (maybe let the days slide by without realizing it) it's gone. It wasn't until later versions that Grim set it so it wouldn't leave your journal after the 7 days. There is a way to reset the flag using the console but not sure what it is. Suggest asking Grim how to do it.Does anyone know how to advance the plot of the "Aimee's good" store?
I have maxed out almost all the store, I helped Dakota with the crooks... and that was months ago.
As I see from the forum I should have received a letter for her 18th birthday, but I don't have any letter.
