This was odd...Logged in to CO.COM tonight and it complained my password/account login was invalid, even though I have autofill on for the entry boxes. I logged in again and it then worked, but it gave me a screen describing the OP account rules and a continue button. Selecting continue it showed my current account properly except it displayed that I have 0 OP miles, but Activity since my last statement properly displayed the 20k in miles I earned over the past 1.5 weeks.

I logged out and then back in then it was displaying the 500+k of miles I have and everything was back to normal.

Very Strange.
