Update library adds whole library not just changes

Updated to 9.5.0 yesterday, updated my entire library to make sure its compatible but now if I make a change to the files and run another update it adds every single file and not what's new.
If all I want to do is add or remove a few files it takes ages to complete.

Could you elaborate the problem a little bit?

Is it duplicating files or something when you update the library?

Running on Windows with library on network drive with full access.
In the previous version if I ran update it would check the files quickly the bar at the bottom "Some of the comics being added" would show some those being added to the library and those files are those which I had moved, renamed or added to the folder. The files it is meant to amend the library with.
Now the bar at the bottom shows most of my entire collection and it is scanning and appears to be adding everything to library again. It looks like it's doing a full scan rather than looking for what has changed since last time.
It doesn't look like anything is being duplicated in the library itself just replaced.

I can't replicate that at all.

Is this happening every time you update the library?

Maybe your library is corrupted or something, it could be that the migration to 9.5.0 went bad.

Every time I update it does the same, I'll move out the ".yacreaderlibrary" and let it scan again and see what happens.

Please keep a backup of the bad library. A bug like this would've been a show stopper if any of the beta testers would've found it.

It could be a writing permissions issue if the db was created as root...

This is what I've discovered in the last 3 hours.

It was updating much faster than a full from scratch update, a full update takes almost 3 hours and a subsequent update with no changes made to the folder takes less than 20 minutes.
On the previous version updates with nothing changed took less than a minute, even adding a hundred files only took a few minutes.

Permissions shouldn't be an issue but just the sake of being sure once the library had been created I checked them and I got Then I ran a chmod 777 on the folder and it turned into
I've restored the old library as it had all my reading progress and nothing changed.

So if you create a new library the problem persist. Can you create a library in your desktop with some comics and see if the same thing happens?

Could you please send me the library.ydb file?
