Quick answer
Start with a compact shelter, capture a before image, leave and rejoin, then compare the same view and inventory. The official description says builds and items save across servers, but your own rejoin check is still the fastest way to validate the current behavior.
Steps
1. Mark a simple footprint
Choose a location you can recognize after rejoining. A small footprint makes missing blocks easier to spot.
2. Build the minimum useful shell
Place a floor, walls and a storage area before decorating. Keep materials visible so you can compare the inventory later.
3. Capture a before state
Take a screenshot of the front view and your item inventory. This creates a reference for the rejoin test.
4. Leave and rejoin
Switch servers once, then return to the same location. Compare the build and items before adding a larger wing or rare decoration.
Use the published save signal carefully
The official description says all builds are saved to private servers and that items remain saved across servers. That is a valuable product signal, but it does not tell us how fast saves commit, how rollbacks behave or which edge cases exist.
A quick rejoin check does not replace official documentation. It simply gives you local confidence before you spend a large mining sample on a permanent build.
- Check the same viewpoint after rejoining.
- Verify both placed blocks and carried items.
- Repeat after a major update.
Scale only after the check
Once the small build survives a server change, expand in sections. Finish one room, verify it, then continue. This makes it easier to identify whether a missing piece is a placement mistake or a persistence issue.
- Keep a simple storage zone.
- Use replaceable materials for experiments.
- Keep combat tests away from your main home until loss rules are clear.
Tips
- Name your screenshot with the date and server type.
- Rejoin after each major expansion until the save behavior feels predictable.
- Keep a small backup supply for rebuilding test pieces.
Common mistakes
- Decorating before verifying the first save.
- Assuming private-server wording explains every public-server edge case.
- Testing PvP inside your only valuable build.
