In Language File "English (UK)" horse armour is spelt incorrectly.

Here I am on "English (UK)" and it is meant to "horse armour" however it is the spelt the US way in the UK language files.

This ticket is a language translation change/add request and is currently not supported on this bug tracker.
Please use the Crowdin Minecraft Translation Project for all translation change/add requests.

But the translation at crowdin.net is correct, the language files aren't pulled into the game. Expect this in the next day(s).
