LavaFix
Stops the vanilla chunk-blending fallback from flooding void skyblock worlds with lava after a Minecraft version update — built specifically for the Skyblock Infinite datapack.
If you run Skyblock Infinite (or a similar void-terrain datapack) and update your server's Minecraft version, you've probably seen it: player-visited chunks get flagged for world blending, and vanilla falls back to its hardcoded default aquifer/lava settings instead of respecting your datapack's noise config — carving giant lava lakes into what should be empty void.
LavaFix stops this at the source:
- Disables the blending fallback entirely. Old chunks no longer force vanilla's default lava-lake generation near your void terrain.
- Stops the "needs blending" flag from persisting. Chunks get cleaned of the tag once handled, so it can't reapply.
- Automatically sweeps existing lava from chunks already affected — one chunk at a time, throttled per tick, as players approach. No lag spikes, no world-wide scan.
- Never touches a chunk twice. Once cleaned, a chunk is permanently marked done — no repeat sweeps, no wasted work.
- Doesn't delete or reset chunks. Only the lava fluid is removed; everything else about the chunk (structures, builds, terrain) stays untouched.
Built for skyblock/void servers where any unexpected lava is a serious problem — not a general-purpose "no lava" mod. If you're not running a void datapack affected by the blending bug, you don't need this.
