Estava jogando tranquilo quando fui atender uma ligação, e quando fui retornar ao jogo me deparo com a seguinte mensagem de erro:
Falha ao conectar com o servidor de atualização (Erro:4)


In english:

I was playing quietly when I went to answer a call, and when I went back to the game I came across the following error message:

"Failed to connect with update server. (Error:4)"

Check your internet connection or try reinstalling the game. Make sure your account is already linked before reinstalling the game or else your data will be erased :p
