Whenever I try to summon a Warden with the "CustomName" NBT Tag, instead of becoming persistant (not despawning/digging back into the ground), it just decides to dig right into the ground.

No sniffing, no roaring, no anything.

Just digs right into the ground.

Also, I've tried different tags like "CustomNameVisible", and even left "CustomName" completely blank! And it STILL digs into the ground :/

I also tried using "PersistanceRequired" on it, but alas, nothing worked.

Is there something that I'm doing wrong? Is it MEANT to do that with the "CustomName" tag?
