Why did my friends disappear?

I have similar problem I disconnected my facebook account and reconnected to the game not all my friends listed only 3 of them and sometimes a friend send me life not in appear on list that mean I appear to him but I can't see him my friend list

which make me really sad.

ALL my toy blast friends have disappeared too! Including my children (only in the game) LOL

Why? I’m active on Facebook, there has to be a reason. I NEED my friends back, I have 3 stars on every level, I’m in first or second place on most I’ve completed all 4050 levels, I’m currently on level 293 in the Legends Arena ....... it’s not much fun without friends, challenging myself to be number one on every level ..... number 1, all by yourself, means nothing! Please help me get my friends back ! Note : I had 247 friends on Toy Blast

I lost all my friends too. I Uninstalled and installed three times to see if I could get them back. Did the whole Facebook thing and It didn't work. The friends I had on there were all active. I don't get what their doing or why?

A response I just received from Toy Blast support: "I would like to inform you that Facebook removed inactive users from the games. This is affecting most of the games that are using Facebook to see the data of the friends. Since this issue is related to Facebook, we are unable to know when they fix it. Once they resolve the issue, you will be able to see your friends again"
