I did contact Associated yesterday and they said a small amount of puff in the pack was normal, as long as the case was not separating, which mine is not, it only seems a bit firm/expanded in the center of the case.
I tried to find a number to call for Orion, but they have no tech / customer service contact numbers on their website.
I am still looking to get a firm answer - are these higher capacity packs more sensitive then the older lower capacity packs?
