My son lives for creating large groups in Cyrodiil, but now when he invites someone, and they accept his invitation, they simply fail to join. The notice on the invited person's screen says they accepted the invite, while on his screen it says they declined. I had him unload all of his addons, click "restore defaults" everywhere I found the option and nothing changes. He can join groups just fine. Also, his alt character CAN create groups with accepted invitations, but not his Main.
Any help or suggestions would be most helpful. Thanks.
