.odg files simply missing from M3 Mac Air finder

hi, I’m having a terrible time with .odg files disappearing on my M3 Macbook air, os 14.3, LO 25.2.2.2
files I know i’ve saved simply do not seem to exist on my computer. I have not deleted them accidentally, I have looked in the Library files for LO backups and there’s nothing related to the ones I’m looking for.
i have found a file that was missing once before, but I cannot recall how and don’t think I understood even at the time how it reappeared.
ods files are not missing as far as i can tell, but I don’t use them anywhere near as much
searching by name doesn’t find them, searching for .odg also doesn’t find them, though there are lots of other ,odg files
it has happened before that I’ve received the mysterious “this file is in use by another instance. open anyway?” message after LO crashed, which it has frequently. I lost a lot of work, but an update to LO fixed the autosave function and I stopped losing the progress. this is different, though - the files are nowhere to be found.
I can go to a private data recovery firm and see what they find, but I’m so puzzled, and actually kind of despondent. It’s happened a lot. Apple has no explanation, but I’m going to the Apple store to see what they can do, which is likely nothing but offer to wipe the disk with an os upgrade…

AMAZINGLY, I’ve found the files by asking Claude how to do it. I used a Terminal window and the command line:

find / -name “*.odg” -type f 2>/dev/null | grep -i “keyword”

They were there, but the finder didn’t see them until forced to by the specific directory path. Thank Claude I thought of asking Claude.

Consider saving files within the folder that Mac expects, the Documents folder.
