Stats are "lost" after a global account rename

[Helder]

Unless some data was lost recently, it seems the stats are kept under the old user name of users who are renamed (globally). In my case, my stats could be attached to the old username "Helder.wiki" instead of "He7d3r".

Could you check if that is the case?

If yes, could you adapt the code to move the stats to the new user name when users get renamed? (or, maybe just a one-case hack for my username?)
