2010 Winter King/Queen Medal causing Lag/DC? And its expiration date?

Describe the problem. Be as specific as possible!:

So, my friends first experienced severe lag after obtaining the extended version of this medal. At 1st, I thought it might have been their internet provider. However, after obtaining the new medal myself, I, too, started experiencing this lag. Plus, the website says the medal lasts for 30 days, but mine lasts for 240 days (Aka 8 months).

(Cannot show a pic of the lagging, but can show the medal)

NOTE: This lag did not start until AFTER I got this medal. Has anyone else experienced this?
