I would not say that. I use OOo at work since 2.0, 4 years ago and never had any problem of this kind. I use OOo 8 hrs a day at work and my documents are from 100 to 500 pages long, 5MB. I only have the OOo backup feature and a backup on a separate HD each week (I know, not often enough).
Honestly, I think that there is a problem that is deeply hidden somewhere. If you see the topic where I've listed all the cases I've seen here, you'll notice that it started with 2.3 (no such bug before) and it's often linked to specific events (power failure, ...).
There are some other cases that might involve other software but very difficult to spot such interaction.
LibreOffice 25.2 on Linux Mint Debian Edition (LMDE Faye) and 24.8 portable on Windows 11.
