I've spent the whole day writing editing a proposal a partner sent as docx. I've tested out writing revisions and saved the file to be sure, and I could re-open it just fine. After some hours, I've sent the file to the partner and he said he couldn't open it. Looks like Libreoffice broke the document.xml file beyond repair when I edited my last comments. Will need to work until midnight because this piece of shit software is incapable of handling the basic document structure it is written for. IF YOU SUPPORT DOCX FILES HOW ABOUT YOUR RELEASE VERSIONS DONT LEAVE BROKEN CORRUPTED MESSES YOU PIECE OF SHIT. HOW MANY HOURS DO YOU THINK HAVE YOU COLLECTIVELY WASTED??
