I have a problem with leaderboards. If a player send a score to the leaderbord using a name already used by a previous player, it erase the previous score.
So if player 1 send a score using the name “Bob”, and then player 2 send a score using the name “Bob” too, the score of the player 2 erase the score of the player 1.
How can we solve this problem ? Is there a way to prevent player to use a name already used ?
