That stinks I'd contact Lodge to see if they've heard of it before. I know they can crack if dropped on something hard (concrete) and that very uneven heating can cause it - but it hardly sounds like that's what happened here. I would be very sad if mine cracked. I have 3 and use them 90% of the time. It also sucks because I think they only sell pre-seasoned now. I'm not sure I like that. Mine took a long time to get conditioned - but they're amazing now.
