Hello, I am working on a new mod that allows users to store local copies of certain chunks and reload them on any given time. (Needed for a custom map) Now my problems come with the reloading. I can get the system to save the chunk to a different location and create a new chunk object from that saved copy, but when i try to inject it into the world during runtime, it will not update the active world. Even if i use a coremod to so that i can write into the loadedChunkHashMap inside the chunkProviderServer the chunk is not injected properly. Is there a way to inject the chunkdata (Blocks, metadata, NBT, Tiles etc.) into the active world without iterating through every block? Thanks for your help in advance, Orion
