Swollen Bandits

[G_Spot]

I have a box of Bandits that I've been using all spring with great success. I went fishing yesterday for the first time in two weeks. When I pulled out my plano box full of bandits, something looked 'off' with the lures. Upon further inspection, almost all of them were swollen to the point of disfigurement and the paint started splitting as a result of the lure's expansion. I attached a picture. Has this happened to anyone else? I'm assuming that this was caused by high temperatures in the box. But only the bandits were effected. None of the other cranks - husky jerks, smithwick's, were effected. I've reached out to the manufacturer. Hopefully they work with me for replacements.
