Why have over 30 in game friends been removed? I presume it is because they are in active players? Now when I have went to purchase my next square of a island upgrade I can no longer pay in gold only in gems as I now only show 4 friends. May be if it didn't take 5 mins to get past all the adverts in your game these 30 odd friends would still be playing your game and wouldn't have been removed from my list. So iam being punished for something out of my control or now have to add strangers to my Facebook list (extremely safe I may add) who could be hackers scamers or pedos for all I know! If you want to remove the inactive friends then remove the island friend purchase cap!!!! If not it looks like you will end up with another in active player level 91 and 4 years into game.
