Server Crash on Chunk Generation with NoSuchMethodError (Paper 1.21.5)

[AdrianPacewicz]

Hello,

I'm experiencing a recurring server crash when generating new chunks after installing Custom Ore Generator. My server is running Paper 1.21.5, and I'm using Custom Ore Generator version 2025.05.5.jar.

The server crashes with the following error in the console:

[ChunkTaskScheduler] Chunk system error at chunk (-20,-14), holder: NewChunkHolder{world=world, chunkX=-20, chunkZ=-14, entityChunkFromDisk=false, lastChunkCompletion={chunk_class=net.minecraft.world.level.chunk.ProtoChunk,status=minecraft:carvers}, currentGenStatus=minecraft:carvers, requestedGenStatus=minecraft:full, generationTask=ChunkProgressionTask{class: ca.spottedleaf.moonrise.patches.chunk_system.scheduling.task.ChunkUpgradeGenericStatusTask, for world: world, chunk: (-20,-14), hashcode: 454779808, priority: COMPLETING, status: minecraft:features, scheduled: true}, generationTaskStatus=minecraft:features, priority=null, priorityLocked=false, neighbourRequestedPriority=null, effective_priority=null, oldTicketLevel=33, currentTicketLevel=33, totalNeighboursUsingThisChunk=11, fullNeighbourChunksLoadedBitset=17318416, currentChunkStatus=INACCESSIBLE, pendingChunkStatus=INACCESSIBLE, is_unload_safe=ticket_level, killed=false}, exception:

I've tested with a clean installation of the plugin (removing the config folder) and a minimal configuration, and the issue persists upon new chunk generation.

My question is, is this a known issue with Paper 1.21.5? Are there plans to update the plugin for full compatibility with Paper 1.21.5 and future 1.21.x releases?

Thank you for your time and for this great plugin!
