I renewed premium in 2017-07 for $24. I expected this to be for one year. However, the expiry in my account states that it expires in 2019-07. It seems like there’s an extra year added to my subscription.
It’s from a bug I fixed three weeks ago. Enjoy your free year!
Hey, I just want to let you know that it seemed to have just happened to me now. I’m a new premium user as of yesterday, charged once, with two years of premium status attributed to my account.
