ChunkBlockSync
About
A Fabric *.21.11 server-authoritative mod that mirrors every player block placement and break to the same chunk-local coordinates in every chunk across the world (optionally every dimension). Uses a tick-spread replication queue to avoid freezing the server, a persistent change history so unloaded chunks catch up when they load, recursion guards to stop replicated edits from re-triggering themselves, and full BlockState/block-entity preservation (orientation, waterlogging, chests, signs). Fully configurable: enable toggle, chunk radius cap, dimension scope, ignored blocks, and debug logging.
