So I have not used this account since the original beta. Looking at Account Management, beta is the only code ever used, and it has never had any paid time added.
Yet somehow, on logging into it I found that the account has 19 Paragon Reward Tokens. That's more than the account I've actually been using, who has 15 tokens after 2 years 7 months of paid time.
..Any idea as to what might have happened?
