At the lower right corner of the screenshot below, an untranslated subtitle "Allay tosses" is shown and I was playing in simplified Chinese. But that string has been translated to simplified Chinese (Minecraft Game - Minecraft - Crowdin translation) and should not be displayed thus. This seems to happen whenever that subtitle appears.

I just realized that the string was updated 5h ago, so it's working well. LOL
