Output corruption sometimes persists across all different modes of printing/exporting. Some lines in Word starting to go vertical for no reason is one I encountered a lot, the other is Excel insisting on making every cell it’s own list, and it’s usually fixable only by force rebuilding the file container by saving as another doc/docx type, pushing Word to make it from the scratch and drop traces of accumulated file corruption. Funny enough, some of these bugs can’t be reproduced if opened in Libre, that made me prefer it, when applicable, a long time ago.
