# OneBlock 5.1.3 *This file is for **NeoForge 26.2**.* Critical fix for **Minecraft 1.20.1, 1.20.2, 1.20.3 and 1.20.4**. If you play on one of those versions, update before you launch the game again. **The mod was corrupting worlds on save.** Every time the game saved, the part of `level.dat` that describes the world's dimensions was silently dropped. Nothing looked wrong while you played — the world only failed the *next* time you tried to open it, with "Failed to load level data" or a crash straight back to the world list. The backup copy Minecraft keeps next to it was damaged the same way, because every save since the world was made had gone through the same path. This was not limited to OneBlock worlds. Having the mod installed was enough: a plain survival world, a world from another modpack, any world opened once with an affected build was left unable to reopen. The fix removes the cause entirely, and worlds saved from 5.1.3 onwards are written correctly. **Already have a world that won't open?** 5.1.3 cannot repair it — the information is gone from the file, not hidden. Restore it from a launcher backup or a copy made before the world last shut down.

The backup copy Minecraft keeps next to it was damaged the same way, because every save since the world was made had gone through the same path. This was not limited to OneBlock worlds.

# OneBlock 5.1.3 *This file is for **Fabric 1.21.6**. It requires **Fabric Loader 0.16.13 or newer** — that is what Fabric API already needs on 1.21.6.* Critical fix for **Minecraft 1.20.1, 1.20.2, 1.20.3 and 1.20.4**. If you play on one of those versions, update before you launch the game again. **The mod was corrupting worlds on save.** Every time the game saved, the part of `level.dat` that describes the world's dimensions was silently dropped. Nothing looked wrong while you played — the world only failed the *next* time you tried to open it, with "Failed to load level data" or a crash straight back to the world list. The backup copy Minecraft keeps next to it was damaged the same way, because every save since the world was made had gone through the same path. This was not limited to OneBlock worlds. Having the mod installed was enough: a plain survival world, a world from another modpack, any world opened once with an affected build was left unable to reopen. The fix removes the cause entirely, and worlds saved from 5.1.3 onwards are written correctly. **Already have a world that won't open?** 5.1.3 cannot repair it — the information is gone from the file, not hidden. Restore it from a launcher backup or a copy made before the world last shut down. The Modrinth App, CurseForge and Prism all keep world backups; if you have one from before the corruption, it will open normally once 5.1.3 is installed. Minecraft 1.20.5 and newer were never affected — that includes every 1.21 and 26.x build. Those are republished here unchanged so the version list stays in step. **CodxLib is required.** Install the build matching your Minecraft version and loader. On Fabric it needs to be 1.3.4 or newer.

# OneBlock 5.1.2 *This file is for **Forge 26.1**.* Bug fix release. **Jumping into a dungeon portal froze the game.** No movement, no chat, no menu, and if you quit you got a crash report. On a server it stopped ticking for everyone. The mod was searching for the dungeon's structure inside a server tick, over an area 32x wider than it was ever meant to be, so the whole game sat there until it finished. The search now runs in the background over a sane area, and the world keeps running while the dungeon opens. The first visit to a dungeon shows "Opening the ...", after that it's instant. Also fixed: * The Pillager Outpost dungeon never had an outpost in it. Its dimension used a biome outposts don't spawn in, so there was nothing to find. It's a taiga now. * Dungeon portals and sessions no longer carry over if you leave a world and open a different one without restarting the game. * Return portals get cleaned up instead of piling up. Server admins: the per-dungeon `searchRadiusChunks` option is now `searchRadiusCells` (default 8). Old values are ignored, nothing to edit by hand. **CodxLib is required.** Install the build matching your Minecraft version and loader. On Fabric it needs to be 1.3.4 or newer.
