Yeah, in vanilla minecraft only first word in entry starts from capital letter, and other ones are not (Example, eng: "Diamond Sword" rus: "Алмазный меч"). Also, resynced my fork.
Current Russian translations make all my friends(and not only them, any Russian people) laugh. They were made using google translate, and most of them are not correct. Now fixed(I am from Russia).
P.S.
Updated it to latest en_US translations.
