Regenerate one or many chunks

Use Regen when a target must update now. For large areas that can generate when later loaded, consider Delete/Prune.

One chunk

/cr regen here
/cr regen chunk <world> <cx> <cz>

Marked batches

/cr mark list
/cr regen all chunks
/cr regen all chunks --confirm

You can restrict the batch to structures or include both normal chunks and structures:

/cr regen all structures
/cr regen all all

Run the command without --confirm first and submit the confirmation form only when prompted.

During the job

/cr status
/cr cancel

Verify

Verify target borders, structures, caves, vegetation, biomes, player/entity and Residence results, and server logs for worldgen, serialization, lighting, or apply errors.
