Net colors in project file are not backed up

Software

Linux Mint, v8.0.1

My pro / project files have net colors. Painstakingly set. Works fine. I had a crash and the project file needed to be re-created. Unfortunately discovered that the "net_colors": { JSON entry in the project file is never saved in the backups. All of my backup files for weeks show null for that entry.

Maybe there was a permissions issue with that file? I’m not sure, but if it could never write the net colors, it should never have come back after a reboot. So it was saving them at least somewhere, but my backups show nothing.

Is there somewhere else those could exist?

I checked one of my projects that uses colors. The net_colors field is null in the active project and the backup files.

Colors show up under net_settings then classes. Each netclass has an entry that includes the fields pcb_color and schematic_color.

For reference, here is Default and 5V Rail. The 5V Rail netclass is set to red. And those fields exist in both the active project and the backup files.
