What steps will reproduce the problem?
1. Two players start a game, one with an empty inventory and the other with the items to duplicate.
2. After the game starts, the player with the empty inventory quits Minecraft, thus forfeiting.
3. When the player returns to the game, he will have the same inventory as the player who stayed.

What is the expected output? What do you see instead?
I would expect both players to have the same inventory that they started with. Instead, both players end up with the same inventory.

What version of the product are you using?
Joust v0.0.1
