there is a flaw in the design(i assume its not a bug)
if you throw the box into the firepit and teleport into it, you will be killed. after press R to revive the player will be spawned in the fire pit, player can walk around, but as soon as you jump, player gets killed, and revive again in the firepit. maybe do some changes so you can throw the box upwards? or spawn at a different area?
