Could you try something for me, please? Try to reload an older save and see if the game updates.
What version are you updating the game from?

It was a new install, meaning the current version based on the time of my comment.
The files worked when I took them out before uninstalling then moving them back after I installed the "current update".
So I think even they (older saves before Layla events) would still work for my phone, dunno about others' though.
Thanks for replying and good luck! We will wait for more story and ecchi.
