SafeSaves

SafeSaves is an early plugin that protects your data from being corrupted through safer file operations. It ensures your saves remain safe during unexpected crashes or shutdowns.

Description

⚠️ IMPORTANT DISCLAIMER

Always back up your world data before using this mod. While SafeSaves is designed to enhance data safety, it is an early plugin that modifies core game behavior at the bytecode level. We strongly recommend creating full backups of your worlds and saves before installation.

What It Does

Imagine you're building an amazing world and the game suddenly crashes while saving. Your data could be corrupted. SafeSaves prevents this by using a smart saving method:

Instead of overwriting your data file directly (risky), SafeSaves saves to a temporary file first. Once it's completely saved and safe, it replaces your old data file. If something goes wrong during the save, your original data stays untouched and protected.

Think of it like making a complete copy of a document before editing it. If something goes wrong, you still have the original safe and sound.

Why You Need It

Has your PC or game crashed, and corrupted Hytale save files or configs? This mod prevents that.

Peace of mind. Stop worrying about losing hours of progress to crashes or unexpected shutdowns. Your data is always protected.

Installation

  • **Back up your world data **
  • Copy the JAR to your /Hytale/UserData/earlyplugins folder
  • Launch Hytale.
  • The mod is automatically enabled for all worlds.

How do you know the mod is working?

The mod should work as long as you've put it in the correct folder. No need to enable anything. But if you don't trust it's working, there's currently only one way:

checking logs in /Hytale/UserData/Logs, when you've launched the game and joined a world, it should say these lines:

2026-01-29 20:57:46.8501|INFO||SERVER - [EarlyPlugin] Loading transformer: com.hypixel.hytale.plugin.early.example.SafeSaveTransformer (priority=0)

Requirements

Java 25 or higher Hytale (compatible with early plugin system)

Note

This is an early plugin and runs before the main game server starts. It performs bytecode level transformations to enhance game behavior. Use at your own risk in production environments.

Performance Impact

Minimal. SafeSaves adds negligible overhead to write operations.
