Blocks, mobs, and items which were add in 22w12a, were translated on different l languages in 22w13a. On russian language Warden Spawn egg is cold "Яйцо призыва надзирателя ", but when Warden kills you, the death-message sounds like: "Player был убит Хранитель ".
It is possible, in the death-message, to replace the word "Хранитель" with the word "Надзиратель". Because it looks very strange and some stupid.
