Small screws on inside bag latch coming loose

Sorry if this has been covered before, I haven't seen it mentioned.
I took about a 110 mile ride today, some highways, but mostly backroads. Averaged around 60-65mph on some less than stellar roads. When I arrived back at the bunkhouse, I opened the right side bag to remove the 'riding kit' bag I always bring along, and the small screw at the bottom left of the inside mounting plate for the latch just popped out into the bag. These are tiny, phillips-head screws and VERY short. I tried screwing it back in, but it wouldn't ever grip. Two of the others on the same row were loose, and wouldn't tighten. I finally got some rubberized cement and re-seated them.
Anyone else have this happen??
