As you can see, the counter on the accolades says i have 8 gold characters when in actuality i have 10 unique gold characters (The collection above was sorted to only golds, from most recent to the oldest).
i first noticed the bug when i got opened a gold relic and a premiere relic to get That's All Folks - Peacock and Surgeon General - Valentine. it showed on the accolades that i only have 7/10 gold fighters, at first i dismissed it thinking it would probably be fixed if i get a 10th gold character. as it turns out, just today after i opened the Back to School relic and got a Lapis Luxury - Eliza as my 10th gold character, i didnt get the rewards and the counter is still at 8/10.
this might be due to the connection issue i had when i was opening relics that got me That's All Folks and Surgeon General.
