The ender quarry in the FTB Infinity pack has a logical chunkloading system built into it where only single chunk is loaded for the quarry to mine. When the quarry completes the chunk, it moves onto another, unloading the previous chunk and loading the next one. The quarry doesn't update fluids, creating a minimal amount of lag. where the main action being done is the replacement of a block with dirt. This system causes little issues and lag. The only time where it causes a problem is when the ender-quarry is used inside the twilight forest dimension, which is known to cause lag.

Recent changes to chunkloaders on the Infinity have barred the use of any mod based loaders and restricted the use to only plugin-based chunkloading. This is fairly logical as allowing access to endless chunkloaders will inevitably result in increased lag. This restriction also stops the ender quarry from chunk loading, making it essentially obsolete, unless one has a tremendous amount of chunkloaders or has the patience to sit next the quarry and let it do its thing.

Seeing as the ender quarry has little lag inducing properties and since it is incredibly useful for any player, it would be a shame to have it be made worthless with revoking its chunkloading ability. The aforementioned ender quarry inside a twilight forest can simply come with repercussions in the future. Please make a change
