First of all, do as I say, not as I do. Back up several times per day :-)
If you ever need to did yourself out of one of these environment reversions,
and if you have a reasonably recent version that has not experienced
environment reversion, you can find all environments used in the old document
like this:
grep "begin_layout" mybook_old.lyx | sort -u
The preceding gives a list of all environments used in the old document.
Remove all article-provided environments -- those did not revert, presumably.
What you're left with is environments that reverted.
Now, in a read only text editor, search the old document for each of those
environments, and obtain some suitable search text with which to look for the
same text in the new (but reverted) version. Apply the proper environment in
the new one.
The preceding is the fastest recovery you can make, but it's ugly. The way out
of this is to back up several times per day.
