I'm curious how many here have had baggage issues this year and in previous years?

Last night's flight is now my fourth issue with baggage on CO. I've had delayed bags twice, a bag destroyed, and last night had a bag CUT which according to them had to have happened from the automated baggage sorting system, but I just can't logically figure out HOW, when the part of the closure system that would have broken was fine, while the much stronger chain part was the one that "snapped" (looks like it was cut with cutters to me though)

The bag I've used for all my travels is a American Tourister garment bag, has travelled with me all over the country, and I've used it tons, but this year has just been havoc.

It folds open and hanging clothes go in the middle, while undershirts, socks, and the like can go in one outside pocket, while another smaller one holds your toiletries. There is two quick release buckles on either side at the end to hold it in a closed position, as well as a hook that doubles as a hanger to hang it up, as well as to hold it shut for travel. There is also a zipper that runs the full length of the bag, to zip up the hanging clothes section.

Last night on arrival at my hotel, I unpack and find that the hook holding the two halves together is missing, and on closer inspection, it looks like one of the links has been CUT, and the hook part is nowhere around. What is strange about this, is that if it truly snagged on something as the CO Baggage person suggested, the fabric loop that the hook slides into on the opposite side of the baggage that the hook is attached to, would have ripped first, before snapping the chain. That is what leads me to believe that the hook was cut off (either by TSA morons or someone up to no good) as the hook is held in place snugly by a velcro double closure, and isn't sticking out from the bag at all to snag on something.

I guess my question is, am I just unlucky this year, or has everyone noticed quite a bit of increased baggage hassles this year then previous years? Also figured I would mention that all of these trips have been single segments, not multiple segment trips, so no real excuse to have delayed baggage, as well as always have checked the baggage in at least an hour before departure.
