[1.8.9] Clientside Chunk Unloader

[Draconwolver]

This may be an odd request, but how would I make a clientside mod that keeps chunks unloaded (prevents them from loading)? Since ChunkEvent.Load cannot be cancelled, I tried using Chunk#setChunkLoaded(false) from within, but that doesn't do anything.

This works to an extent, but I don't think it is what I was looking for. The chunk unloads, but my client is still able to stand on the unloaded blocks and select them:

Is there a way to mimic the effect of "lagging out" on servers where chunks are unloaded and all the blocks in them?

[Draconwolver]

It's just for recreational purposes, I want a way to artificially lag myself.

Would there be another way, such as just tossing out incoming packets that update the chunk?
