Hi Dia
Disconnecting and reconnecting didn't work?
Then if both fb accounts still exist follow these steps:
1. Go to your device settings, choose the facebook menu and disconnect the facebook app your former account is linked to (in iOS it says "delete account"; but don't be afraid, it is not meant to delete the fb account, only the connection with your device)
2. Go into your former fb account, choose "settings > Apps" and disable the permission for apps to access your fb account (if several apps use your fb account you also can delete the township button only, but the safer working way is to disable the general permission). Then log out your account.
3. Go to your Township app and disable "connect to facebook" in your settings (the cog gear on the left top). Then close the Township app
completely (means, not only minimize; in iOS doubleclick the home button, then slide the app away to the top).
4. Go to your
new facebook account and inable the permission to link apps to your account (same settings like step 2.) Then log out the account.
5. Open Township and inable "connect to facebook".
The game now will ask for log in your facebook account; choose the new one and your game will connect it.
(If you have problems with this procedure please feel free to come back and we will troubleshoot together; there are some more possibilities depending on how you are linked in detail between device/game/facebook. )
