Normal
Yes the red bottom ones where made with two separate pieces of plastic that cracks where they come together, I have a red bottom one to and it also cracked. I asked vexilar if I could trade it in. No dice so i asked on another forum if anyone had been able to fix the crack problem they said use something like jb weld for plastic. Make sure you get all the moisture out of the inside before you seal it up after that it should work again.
