The localization system has changed and it's a bit weird now. For exemple I downloaded rueso, used the ru in the seetings but at first it loaded in English i had to SetCVar in game. then even when i went back to English my french special characters still displayed in russian .

I don't know how you got it working in English but you are comparing an untranslated name with local TREASURE_TEXT = {
en = "treasure map",
de = "schatzkarte",
fr = "carte au trésor",
ru = "êapòa coêpoáèû",
}

and there are several ways of "changing" the langage, do you use SetCVar ingame or do you load the complete client in another language for you tries? I doubt users have 40Gb extra just for a (third) language? and chip said that the default "untranslated" would be English, but that is probably only when you load the client completely.

anyway, you can check if it's a map/Survey if it's blue, bound, unique + usable etc.... now that mobs trophies ain't usable anymore. (unique to exclude the new counterfait pardons)
