Quick answer
House building, build saves, and cross-server item saves are advertised, but no limits or recovery steps are published.
Lucky Block World Building Save Guide
Plan a house, use a free private server for build saves, and expect item saves across servers. Setup, costs, limits, and recovery behavior remain unknown; use the build estimator for a simple shell only.
Action steps
Keep a simple build outline, check the private-server prompt in game, and test saves with your own items.
Common mistake
Do not turn the advertisement text into a claim about block costs, item exceptions, or automatic restore behavior.
Plan a rectangular shell
Use the estimator for dimensions and opening deductions only. It does not know current in-game limits.
