I have also found bubbles inside a Storm Trauma, unfortunately on the inside of my thumb hole, size of a bean and just in the place where I use to grip the ball. Not nice for handling. In the first place I filled the hole with nitro filling compound used for car bodies, which is a great stuff for this occasion, and flattened it with wet sandpaper and a white pad. Works great.
A friend of mine found a similar bubble in another Storm ball, inside of an X-hole. I am not sure if this is a common Storm occurence?
I do not think that bubbles in the core material pose a problem, since they do not hamper stability, ball integrity or weight distribution. But it is annoying and can be a real problem like in my case, when it hampers you handling the ball properly.
