No death message for being slain by Nautilus (but only for me?).

If I get slain by a Nautilus (excluding Zombie Nautiluses and variants), the death message will just pop up as “Player was slain by”.

(FYI my username is HunkyDory42 and my UUID is dd06c58e-3b28-4ad0-9e92-7ece404df0f3)

Steps to reproduce:

1: Find/spawn in a Nautilus.
2: Punch it so it attacks back.

3: Repeat until you die in-game

(it’s impossible to reproduce because it seems to be tied to my username or UUID)

Expected result:

The death message says “Player was slain by Nautilus”.
Actual result:

The death message says “Player was slain by”
