Forum:Name randomly changed

After I made an edit on the Skull of Gul'dan page I went to recent changes to see what other articles had been recently changed and I noticed that it said that the edit was done by X59 (my curse name) when my earlier edits for Wowpedia always said Sairez. I then checked and its changed edits that originally said Sairez into X59 went, this change went to at least least September 19th, 2013. Does anyone have an idea on why that happened or experienced something like this before? --X59 (talk) 23:45, 6 December 2013 (UTC)
 * The upgrade to mediawiki 1.21 removed the displayname extension that Curse was using. Alas, unless you change your Curse username (you'll have to go through Curse's support site), there's nothing we can do from this end. Sorry about that. -- k_d3 00:26, 7 December 2013 (UTC)
 * Oh..well thanks for explaining why this change occurred KD3.--X59 (talk) 03:39, 7 December 2013 (UTC)
