We have a Paper server with DeadChests and Minepacks. Our problem is, that all Items including the backpacks get put into the deadchest when the player dies. As the player gets a new Backpack on respawn, the number of backpacks increases with each death (after picking up the DeathChest).
Throwing away the backpacks is not possible even though I have 10 by now.

It would be nice to add a either a possibility to throw away the backapacks (if there is more than one in inventory) or to give an option to deactivate new backpacks on respawn.

Please enable the ImproveDeathChestCompatibility config option.
Also if you stack them up the additional copies should be removed when you join or switch world the next time.

whoops, i missed that one. sorry and thank you!
