I have a LBGE that I bought about 4 years ago. I noticed the other day that it seems to be cracking in half. The crack is visible from the inside as well as from the outside, so it goes all the way through. I keep waiting for it to just crumble while cooking on it. I'm sure this isn't normal but does this happen much? I'm pretty pissed. Unfortunately, I bought this online right before they came out with the edict that they won't warranty such purchases. (as if that would cause it crack 4 years later).
