Guys, a little advise if you didnt moved to latest update yeat.
Do not update until you take Kali on high lvl of friendship (at least 20 or so, preferably complete her available story line). Me myself got a problem with Kali because of moving to the latest update and I had start game all over again. She was stack on lvl 13 of friendship and no new events for here were available even when I already finished most storylines of other girls (all Kali's stats were already 50 or higher). After I started new game everything went further without any problem. So be careful with this.
