First commute in a few months with my old bike. I just set it up with a rear rack and a pannier. I was excited to give it a try, as I've always used a messenger bag to haul around my work clothes and lunch. 1/2-way between the office and train station I had an epic failure which could have been really bad. The nut came loose from the bolt which attached the rack's left stay to the braze-on near the hub. the rack stay came loose, and my pannier got sucked in between the seat-stay and the spokes!! Fortunately, it didn't seize up and the friction just burned a hole right through the bag. The rack-stay was a few cm's away from diving into my spokes which would have shredded the whole back-end. A few of my spokes loosened up but no major damage. I bungeed the bag and right stay to the top of the rack and proceeded to the office.

Finding a nut at the office which will fit the bolt I still have will be a fun lunch project. Maybe a zip-tie will provide a temporary fix?
