So, as I have just found out, if someone invites you to a league and then disbands it, you cannot accept nor refuse the invite, and have to force-close the game as you can no longer click anything. Might wanna look into that.
Turn ignore invites on. Then turn it off when you're absolutely sure your going to join someone's league.
Then why open the thread in the Gotham City sub-section, instead of the Arkham Asylum (Bug Discussion) sub-section?
