Every container the node-agent starts gets /usr/sbin/docker-init, and SteamCMD rewrites its own config.vdf on every run. Counted as files written outside the volumes, they made every build look like it loses saves. A folder whose only changes were logs no longer counts either, and a folder followed by a same-named file (worlds, worlds.bak) is no longer taken for a file.
