hi I noticed when I save a mod , even if I just placed something in a room , it changes the language of name of this cell to english , altough my version is in Italian , how I do a patch translation to italian back? how do I setup the editor to work in italian?

I hope I understand you right. You want to make the CK use the translations of your game? You have to tell it in the editor.ini which language you use. For instance for me it is German, so I copied the "sLanguage=GERMAN" from the skyrim.ini to the editor.ini (under General). Now I have all the names of items, cells etc. in the CK in German translation.
