So, long time ago I used to play on the south america server, however, my friends invited me to join them on the new North America Server, I could not pass the family creation screen because it was saying that name is already been used somewhere (I tried all crazy things with numbers and letters). So I tried to create a family on the old server north America, and guess what? The first name I typed it worked.
TLDR: None of my friends can create a family on the old server and I cannot join them on the new server, what should I do?
