Recent update and sign in issues

I'm having the exact same issue. Very frustrating. I have three alternates, and all go back to first year of the game - so a lot of investment. I hope this gets resolved quickly and stops happening altogether, quite frankly, because they have the money to invest in making sure the game is more stable and reliable than this. This is the second time in the past six months that I've had login issues, and I'm getting fed up with it.
