Blank text bubbles for adventure awaits

Does anyone else has a problem with blank text bubbles for adventure awaits? I live in the Uk but i prefer to play in polish as its my first language. When i buy expansion pack i always make sure i buy one thats not locked for specific region and has a multi-language option. Had this issue before and all i had to do was copy a string language file to delta file. Although this time i cant locate the language fule at all. Can someone help?
