The default language file and %item% placeholder returns the material name, not the nexo itemname for custom nexo items. This takes away from the immersion, as a beachball gets referred to as “LEATHER HORSE ARMOR”…
A non-perfect workaround that I am currently using is removing the item, and just writing “that item”, but I would prefer to be able to display it with the proper custom item name.


The ‘minecraft:item_name’ property support has been added in 1.109.0 and should work for any item, including Nexo items, that use this NBT property instead of the old item name property.
