Time for another rollback?

I was unable to login on my first few attempts and I was sure I was using the correct details username and password. Then I remembered when I entered my new password on the account recovery page, I typed the password into notepad and then copied and pasted it into the boxes instead of typing it (because I couldn't be bothered typing it twice). So I tried copying and pasting the password in the box and I was able to login.
