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.
