SpawnSure

SpawnSure keeps a private history of each player's five most recent personal respawn points.

Use /spawnsure to check the current personal respawn point and saved-entry count. Use /spawnsure history to list recent dimensions and coordinates, newest first. If a player directly breaks an online player's active bed or respawn anchor, SpawnSure warns that player and keeps the last-known coordinates in the history.

The mod records accepted bed, respawn anchor, and forced personal spawn changes after installation. It does not change Minecraft's respawn behavior, teleport players, or select an older point after death.

Histories are stored in data/spawnsure-history.json inside the world save. Commands expose only the executing player's history. SpawnSure has no telemetry and makes no external network requests.

Requirements:

• Minecraft Java Edition 1.21.11
• Fabric Loader 0.19.3 or newer
• Fabric API 0.141.6+1.21.11 or newer
• Java 21

Install SpawnSure and Fabric API on the dedicated server. Connecting players do not need the mod. For singleplayer, install both files in the local Fabric instance.

SpawnSure cannot reconstruct respawn points accepted before installation. Indirect destruction by explosions, pistons, commands, world editors, or other mods does not produce the immediate warning in version 0.1.0.
