Just wondering if any of you have expeirienced Easton Axis arrows bending after using them.

I bought a dozen last spring and spun them to find the straightest ones. Came up with the four best to use with my broadheads and also used them to shoot 3D. This spring, I have been having some consistency issues and spun those four again and three of them were bent! Am I going nuts or has anyone else seen this happen?
