Unplayable once signed up. Got through the Bronze to Iron age in the first week, I've been enjoying this so I "signed up" by adding a password to my "Guest" account. I am no longer able to sign into the game "account not recognized". I select "continue playing as guest" and it says "incorrect password" (because it's trying to log on without one). I've stopped the game, I've rebooted my phone, it's Literally, frustratingly, unplayable.
