I know that won't help you /right now/, but I had similar problems in
the past, and I pretty much got rid of them by commiting all my Org mode
files to Git every day (well, almost every day - my average over the
last 640 days is 0.90 times per day, although I'm getting closer to 1
recently).  It would be great if Org mode had some way to warn me when
I delete something that is invisible (or undo in invisible parts of the
buffer), but I know of no such feature, so I do what I do.  It takes
literally a minute or two every day, and I find it a very useful habit.
