Similar problem when not packed.

I store all my tents together in a loose condition inside a huge box (no folding, no rolling, no packing of any kind when in storage). All of them have been doing fine for years, but the rain fly of my MSR Hubba has turned gooey and a bit sticky to the touch after just a few years. It started happening after about two years, if I recall. It still works, but I can see how leaving it tightly packed for an extended time would be a disaster. The stuff bag, which is made of the same material as the fly, has had the same thing happen to it.
