Have you signed-in with Steam and it has logged in to the wrong/different Robocraft account?
It is likely the Steam link has been removed, changed or switched to another Robocraft account. This means you will no longer be able access the account because the Steam link has been changed.
This can lead to some players believing their game data has been wiped. This is not the case.
If this has happened and you would like to restore access to Robocraft account via Steam, please provide us the information in this article <insert article link here>.
