[SCRIPT] Need some help restarting map!

[TexMex]

Hey, I need some help with my story, or the scripting for my story. The problem is that i need the map to restart when the player dies but i cant figure out how to do this, i tried to put a checkpoint in the beginning of the story but then the player already had the knife (after he died) that was supposed to teleport him when he picked it up.

So do anyone know how to restart the map when the player dies?

Thanks for all help
