The game is very nice compared to the original engine, but... even though I installed the Italian version (and I imagine I have the same problem with languages ​​other than English), the menus, objects, etc. remain in English, while only the dialogue is translated into Italian.
Is this correct?

same issue with plolish language. To be honest if the mod has limitations while adding translations then in my opinion these translations should not be included in the first place. What's the point of adding translation if only half of the stuff is translated
