Reproduce: 1. Have a two page PDF file and open it with Okular 2. Create an annotation on page 2 3. Move the annotation to page 1 4. The annotation disappears. It can now only be accessed from the "Reviews" tree view where it can be edited and deleted but not moved to make it visible again.
I can confirm this.
Yeah you're not supposed to move annotations between pages, AFAIR there's code to prevent that, but i guess it broke at some point
still happens. very annoying :( but I posted here: https://bugs.kde.org/show_bug.cgi?id=432458 mine could be a duplicate of this bug
