Due to the number of problems with the Facebook application it has been disabled, so you can no longer connect your game, nor invite friends via the application.
The regular invite venues are still open for use though, and you can still use your invite code on Facebook and other social networking sites. We thank those who have used the app to invite their friends and hope to help connect your Facebook friends again in the future.
Until then please use the regular invite methods available to you and have fun playing Bloodline Champions with your friends! *hihi*
