ItemMeta apply is a destructive process that expects to be the authority on what the items NBT data is. When CraftItemStack.asNMSCopy was called, the conversion ran, potentially setting the converted data into the ItemStacks tag. Then if that item had ItemMeta, it would completely undo that conversion by erasing the NBT Tag. On copy, run conversion post ItemMeta apply.

Subject: [PATCH] Process NMS Data Conversion post ItemMeta on Copy
|
|
|
|
ItemMeta apply is a destructive process that expects to be the authority on
|
|
what the items NBT data is.
|
|
|
|
When CraftItemStack.asNMSCopy was called, the conversion ran, potentially setting
|
|
the converted data into the ItemStacks tag.
|
|
|
|
Then if that item had ItemMeta, it would completely undo that conversion by
|
|
erasing the NBT Tag.
|
|
|
|
On copy, run conversion post ItemMeta apply.
