Upgraded to 6.7.1 - got DB corruption issues with a bunch of containers: Plex, Unifi, Sonarr, Radarr, etc. anything with a db file inside appdata. Everything was fine on 6.7.0
Downgraded to 6.7.0 - same issue persists. On docker settings, manually switched the location of appdata from /mnt/user/appdata to /mnt/cache/appdata and suddenly everything works fine.
additional details about my cache drives: 2x NVME drives formatted BTRFS running in single mode to maximize available space.
