BUG: Acrobat DC randomly making text or images disappear when changing reading order
When reordering the reading order of items on the pages of an audit report, Acrobat randomly removed text on pages that I wasn't even looking at. I tested it out on another file and discovered the text disappears when you hit save. Up until then everything appears fine.
Acrobat was also making random layers of embedded pdf maps disappear when when trying to add alternative text, and there is no option to simply edit the SLUG text instead.
