Ok so If you have a facebook account and you are logged in from somewhere else you are not able to log into your acount unless you log off the other acount from that computer. When it tries to log in on facebook it says to log in again to boot off the other player and the only way to log in again on facebook is to refresh. Once you refresh it gives the same message to log in again. I dont think this is to much of an urgent fix as long as you make sure to log off your acount on one computer before playing on a different computer. (I'm not sure if the bug is only on my computer or if other people have had this)
