Yes, link it to Facebook before you encounter game-breaking bugs. Preferably as soon as you get through the basic tutorial content in Y1. Hindsight is 20/20. You can certainly try to connect your save to Facebook now, but if it doesn't work, you'll either have to grin and bear it or start a whole new save.I have the same issue but unfortunately my save isn't linked to Facebook so uninstalling and reinstalling the game isn't a solution because I'll lose all my progress. Using the 5.2.2 version to login will also lose my save (because of uninstalling). Does anyone know any other way to fix this?
