Re: Sims 4: repair changes language; missing text strings
@Sylmos Unfortunately, the only fixes for this issue are repairing and reinstalling. But if the only affected items are from Growing Together, you could try deleting and reinstalling just that pack. Each one has a folder inside [install location]\The Sims 4; Growing Together's folder is EP13. So delete that, clear the EA App's cache:

Restart your computer, and download the pack again.
If you still don't have the proper text strings for Growing Together, please open that EP13 folder and post a screenshot of the contents.
