The friend list in candy crush saga on facebook has only me?

Same here, and same to a whole lot of people. Seems to me this is a technical issue on your end (my privacy-settings haven't expired or anything). One moment my friends do show, the next moment they're gone (for a couple of hours, then they're back again, but just to vanish again). Tried clearing cache, didn't help, a different browser doesn't help. Please do look into this...
