The game uses two different names for the Strider in the Russian localization:
• "Страйдер" — used in the Spawn Egg name, mob and achievements.
• "Лавомерка" — used in Subtitles.
Suggested Fix:
Replace all instances of "Страйдер" with "Лавомерка".
Steps to Reproduce:
• Set language to Russian.
• Check the Strider.
