Ruh roh..... I don't even want to think about what kind of a mess that was!!! ;-)
Thankfully I discovered it while cleaning it BEFORE I started using it. I hadn't used it in a while and so wanted to clean it out and found it had gotten a big ding in the bottom and that ding had a hole in it.
I learned my lesson and am much more careful of my storage of them, and more careful of the quality of them.
