FYI: This is a know limitation of the LaTeX exporter[1] and the
current state of this issue (dealing with skipped levels) is that
patches for the problem are welcome. I agree that even if
skipped-level-headlines are not allowed, they shouldn't be silently
droped neither.
Best,

I think I have a patch for this, see below. I've tested it briefly to
see that it works with both oddeven and odd level headings, but I would
appreciate other people taking a closer look/checking that it doesn't
break other things. I think I found the problem, in that if you have a
structure like
* A
*** B
(i.e. a level one and a level 3)
after it has found the level 1 content, it expects to find a level 2
subtree, whereas in fact there could be a level 2+ tree. See the
comment in the code for the change I made.
