Fluxion

0.22.1 — world generation and fog fixes

Minecraft 26.3 and 1.21.1 · Fabric and NeoForge · Java 25 / Java 21

A patch release with fixes from a player's report. Thanks to the player who sent their logs — they led straight to the causes.

Fixed

• World generation error on 1.21.1. The ink ponds of the Inkpine Forest could stop world generation with «Requested chunk unavailable during world generation»: players got stuck on «Loading terrain», a dedicated server crashed. Fixed on both loaders; chunks that failed to generate will generate normally after the update.
• Swamps cut into strips. Around every Stagnant Backwater, vanilla swamps were left as ribbons about 30 blocks wide. Now the Backwater takes the warm side of a swamp, and swamps keep their size, as without the mod — also with Terralith and Tectonic. Only newly generated chunks change; land you have already explored stays as it is.
• Next to Unbound on 1.21.1 Fluxion's biome and dimension atmosphere (fog, sky, light) did not load, and each mod treated the other's dimensions as its own. Fixed on the Fluxion side; Unbound gets the same fix in its next release.
• Fog after a lag spike. After a stall of the game, fog could swing back and forth and linger for many seconds, then close in to nothing. Fog distances now stay bounded: the mod's fog never closes in nearer than 16 blocks, and the mod's biome fog clears at the same pace at any frame rate; on 1.21.1 biome fog also fades smoothly at the biome's edge in rain.

What to do

• Replace the 0.22.0 jar with the 0.22.1 one for your game version and loader (…-neoforge-1.21.1-0.22.1.jar and so on). Worlds carry over, the required mods stay the same.
• A world that stopped at «Loading terrain» opens again with 0.22.1.
