When I save a page on nl.wikipedia with visual editor (Chrome), and try to edit the categories using the HotCat extension, two situations can occur:
- hotcat doesn't load properly, and doesn't show the (+) in the category bar.
- hotcat does load, but tries to edit the previous version of the page (before saving through Visual Editor) - basically reverting the previous edit. This triggers a warning "warning you're editing an old version of this page. If you continue...". After reloading the page, everything works fine.
