Subject: [PATCH] Fix numerous item duplication issues and teleport issues
|
|
|
|
This notably fixes the newest "Donkey Dupe", but also fixes a lot
|
|
of dupe bugs in general around nether portals and entity world transfer
|
|
|
|
We also fix item duplication generically by anytime we clone an item
|
|
to drop it on the ground, destroy the source item.
|
|
|
|
This avoid an itemstack ever existing twice in the world state pre
|
|
clean up stage.
|
|
|
|
So even if something NEW comes up, it would be impossible to drop the
|
|
same item twice because the source was destroyed.
