What do you mean when you say "categories were deleted"? Where did they appear and when did they disappear?
It has been occurring to me in the last translations, too: even if you set the categories in the translation tool, they are missing in the published form.
I translate article via tool, at the beginning they are auto-translated categories. I add new categories to article, I show they in the translation tools. Than I click "public". The new article has the auto-translated categories (from the very beginning, but the categories, which I added, they are missing. When I return to the tool, the categories are missing too.
Thanks for reporting this, @Pavouk. This looks like a bug. It's now filed here: https://phabricator.wikimedia.org/T242613
We'll try to fix this some time soon.
