Any Libre Office users here? [View all]

I've been working on a novel in LO Write. Yesterday I saved my work and made two backup copies. This morning I opened up the file to find that the last two days' worth of work were gone, including on the backups.

I wrote a post in their forum, but wanted to ask here too. Is there a limit to how many words a Write file can handle? I have over 56,000 so far. Or is there a way to recover what's lost? I've looked all over the computer and can't find any backups.

Thanks.
