It gets me stuck in the ground, with a yellow arrow and Comic Sans font that says Bad Data and I cannot move. I cannot dismiss the Bad Data mount and I have to restart my game.
I have this same issue.
I went to the Stable Master and the Mount and the cosmetics that came with it are gone. Which also means my money is gone!!! Please fix this or refund me!
I’m also having the same issue. Mount, armor and trophies are all gone. I still see the transaction in my account.
I just did a “Scan and Repair” and it’s back. Not sure if that’s the answer or not, though.
