Divi user here, too. Not quite the same issue, but seems related…
On BLACK FRIDAY (with promotions running), after updating my home page (which uses Divi Shop Modules), the slug was replaced with that of a somewhat recent post… and the home page got mangled. Rather than go through the heartache of restoring a backup and dealing with an outdated orders database, I rebuilt most of the home page, updated… and the fucker did it again.
All software was up-to-date.
On a separate, but closely related note: Is there any possibility that WooCommerce will develop a simple solution for syncing databases between live and staging sites? I imagine MANY of your customers (including this one) have no practical choice but to update their live sites, fingers crossed.
