We have exposed a new setting in the LootLocker Console to allow you to configure whether or not the player name should be updated from the Identity Provider (eg. steam) when a session starts.
This is useful for games that do not want to update the player name on every session start, but only when the player explicitly changes their name in the game.
This setting is available in the Console under in "Game Settings", under the "Misc" tab. Look for "Preserve Player Names on Session Start".
