Goat horns with any NBT data but without the instrument NBT data fails to play.
- /give @p goat_horn
- Rename the given goat horn using an anvil.
The goat horn would still play.
The goat horn no longer plays.
I named my Goat Horn using an anvil after that, I tried using it, but I can't blow it anymore. No sound comes out, nor does the animation for it work. It's just a useless object now.
