Become an enchantment table font

(I'm using Google Translate: Japanese to English)

In spectator mode, the structure of the undersea temple was confirmed. I thought about defeating the Elder Guardian with /kill @e, but I was also defeated.

And if you look at the log where the mob is defeated,

All were enchanted table fonts.

Then, the title screen went wrong, and I thought it was an urban legend, so I ended Minecraft once and opened it again.

Then the bug was resolved.

There is no problem with normal fonts that are different from Minecraft fonts.
