Hi,
where are you storing your score. If you aren’t doing that already, try soring it in the PlayerState. It presists even if you destroy and spawn pawns.
A PlayerState is created for every player on a server (or in a standalone game). PlayerStates are replicated to all clients, and contain network game relevant information about the player, such as playername, score, etc.
The PlayerState can be accessed via the PlayerControllers PlayerState variable.
