Hello
You should be able to press Salka during the 2nd month. There's an event at atelier lvl 9 where Senna says the stone is ready.
I'll look into the photo events no appearing, maybe the photo data isn't being reset properly when starting a new game so they don't play. I'll let you know if I found something.
If you'd like to try again and don't want to start from the very beginning, you could select "new game" and select "countdown" which sends you to the middle of the 2nd month. If you do then please close the game or web page and open it again to reset the photo data. If you're on android and you should close the app.
Thanks for letting me know. Maybe I'll have a fix ready today.
