I'm thinking I may have fried my gasket. I'm attaching some photos.
I've only had my egg about 6 weeks. I first noticed it after I cooked pizza the first time, using the plate-setter with legs turned down, and my pizza stone. I was cooking at around 500-550. It got worse the second time I did pizza. Prior to the gasket getting in this condition, I had only used the egg for low-and-slow smoking, and twice for pizza. I've done a couple of hi-temp steak cooks since.
Do I need to look at replacing the gasket, and if so, what am I doing wrong so I don't repeat the problem?
Also, as you can (hopefully) see in the last photo, the top and bottom of my egg don't sit perfectly squarely. I loosened the top band, recentered it, and retightened the band, and it's still off by a 1/8". Is this normal, or should I be concerned?
