A very strange little bug has appeared, my rating timeline starts from 1970. For now, I haven't found anyone else who has encountered this bug (of course, I haven't really tried hard to find).
If you click on this link soon enough, you should still be able to see this interesting little bug :

Hey HHY_zZhu, your email-id is visible in your screenshot. I don't know if you'd prefer that.
UPD: Bug has been fixed now.
Had something similar. Now I'm waiting when my specialist rank will be returned :)
