There was a Facebook login issue few days ago so when I re-enter the game, the game asked me to sign in to Facebook again.
But when I pressed sign in, I realized all my friend's player has resign from my team because my save game has linked to a different Facebook account since my friend login to Facebook on my iPhone Safari.
Then I tried to log out of his Facebook, login back into my own Facebook again and enter the game. But my Facebook has now been assigned to a new save game starting all over from Lv 1 again! Which my old save game has already reach Lv10!
SO my original Lv10 save game still exist but it got linked to a different Facebook account. How could that even happend?
This is very frustrated, PLEASE HELP!!!!!!!!!!!!!!!!
