Best Of All Possible Worlds Glitch

[SpaceHamster]

Recently I checked my achievements and it said I had the achievement listed in the title. I've never gotten this before yet I have it. My username is SpaceHamster is there any record of the World of the days? The weird thing is I stopped playing for a few months and I am sure I did not have this before I left. So it must have happened some time within the last 12 months. If there is a record can someone tell me? I count this as a glitch because i've never had WOTD making it a possible glitch.

It was a glitch that occured some months ago I actually don't remember the date. I even have it. Just enjoy a free achievement.
