How to reset a blueprint ?

Currently making a trap like game with checkpoint system, one of the traps is a falling tiles room, with a checkpoint right before.
The only current problem is though, if you fall and die, you will respawn to the start of the trap but the trap hasn’t been reset see picture

The moment player hits the checkpoint save all position of tiles. Then when player dies and respawns restore the position of tiles just as you set position for your player.

Either you destroy all the actors and recreate them in a custom event.
Or you reset all positions in stats in the object using a custom event.
You would trigger the custom event when you die.

Basicly, you need to specifiy when to reset them and how.
