A few weeks ago I setup leaderboad sets no problem for the app I am developing. It was working great in sandbox. Something changed recently. When I go to the app's iTunesConnect page, there are now a ton of errors.. about 1 for each leaderboard saying "Leaderboard grp.myAppLeaderboard1 is not a member of a leaderboard set attached to version 1.0."
I have all leaderboards as members of my leaderboard sets. I am so confused. I can't make any changes to my iTunesConnect page because of these errors. When I try to save, I get an error saying it could not save.
I was able to delete all my Leaderboard sets, and it was able to respond and save again. I went through the long process to make them again and add all my leaderboards to the sets. It still worked. Then I added the leaderboards sets to the section "Leaderboard Sets" for review and bam! All the errors showed up again.
I don't get it!
