Just switched from my main to my alt, to my surprise i have every single mission unlocked and beaten on madness, even the secret locations are unlocked! Im pretty sure i cant have possible beaten the beast yet cuz i still have a 4* team with 4* taismans.
The achievements for GR, the leendary soul and boss battle victories are all locked too, pretty weird, too bad, wouldve liked to get a GR when i can barely beat hard of darkness on hard!
I can even play the levels so its not a server or visual error. I guess shit cuz now i cant get GR...
Here is some evidence
