Hey guys. So I've caught all 13 fish, mailed them, and have been waiting over a week in game time, still no invitations at the post office. I've checked the fish compendium and it is showing I actually have 14 legendary fish caught, with the lower left corner missing (which I assume will be for the massive catfish once I go fishing with Gill. ) I have no idea why I have not received the invitation yet. Online says it arrives in a few days. I've checked the mission progress and it shows all 13 fish caught and mailed. Thanks!
