Dear Team,
I’ve been using Draw 5.1.4 (Libre Office) to create a multi page document (15 pages). It is a college work with many pictures and drawn elements and, after saving the finished document, I closed everything, shut down my computer and went to bed. Today I opened the document (and other two backups I made) and several images of the document (including some drawn elements). I am Using Ubuntu LTS 16.04.
