Thats just it.

When I try to save by going 

Menu->save->saveslot (empty or already taken, doesn't metter)

i got that rejecting sound and no save is created or overwriten

fix it as fast as possible, please

i love your game

PS.: Starting  NEW GAME or changing location of game files does not help

Ater 5th Re-download got it to work properly

Sorry for the late reply! 

You'll need to copy and paste the whole save folder to completely transfer everything. 

By the way, the problem with not saving accurs, when you make game files "hidden" in file explorer settings :)

I can't upgrade Lena to lv2 there is no interactions when she ask for tea at night
