How do I recover a newer Valheim world save without overwriting it?

A crash in Valheim seems to have rolled progress back. There may be cloud and local copies with different timestamps.

What is the safest recovery order before opening the game again? Please include Vulkan mode, world saves, dedicated servers, and large-base performance and a clear warning about overwriting saves.

Stop launching the game until backups are copied.

1. Copy the complete save/world directory somewhere outside the game folder.
2. Look for `.bak`, `.old`, temporary, or cloud-conflict copies.
3. Compare modified times and file sizes.
4. Disable cloud sync before restoring anything.
5. Restore into a separate test slot or duplicate world name when possible.
6. Once the newer save opens correctly, exit and back it up again before cloud sync returns.

For Valheim, the risky areas are Vulkan mode, world saves, dedicated servers, and large-base performance. Repeated launches can rotate backups and make recovery harder.
