What is account linking?
Your Nexon ID stores one set of game data, and linking your Nexon ID account, with stored game data
to each platform, allows you to play on those platforms with the stored game data.
Therefore, if you can't see your game data after linking your account, it doesn't mean that
your game data has been reset, but simply linked to the game data stored in your Nexon ID as described above.
In this case, you can set your preferred game data as the Primary Account at official website > My Info > Primary Account Setup and play with that game data.
For more information on Primary Account Setup, please check our announcement!
