Remember to cover the basics, that is, what you expected to happen and
what in fact did happen. You don't know how to make a good report? See

Your bug report will be posted to the Org mailing list.

I've been having a problem where some of my exports get truncated
randomly at the end. I haven't been able to figure out the exact
problem, but by bisecting org-mode I found the problem appears in
072ddbc9 which sets `org-element--cache-self-verify' to t. By setting
this back to nil manually the truncation goes away, but the warning then
appears.

Interestingly I can only reproduce this when running emacs in batch
mode, not in regular mode.

I know ox-hugo and caching has come up before, but I don't think this
was the same problem as before.
