M20 Ti resin dome loose on LED?

Hi guys, need your help. I was changing the reflector on my M20 Ti and noticed that the resin dome on the LED was loose. I've contacted the retailer re: this but I was just wondering what might have caused this. Would heat be a factor? I can't imagine that for my particular case that it would be the cause since I've very rarely used this light due to it's sentimental value and shelf-queen status and certainly never more than a few seconds to show it off.

This is a bummer as I was ready to do a review on this light too... :mecry:

Cheers,
Tim

probably a manufacture defect
