This mod adds chunk regeneration using the /regen command. Regeneration starts on the chunk the player is standing in, so running /regen 0 will regenerate only the chunk the player is currently in.
KNOWN BUGS:
Structures are not regenerated
When regenerating a chunk with trees multiple times, leaves will not be removed. This is intentional to prevent half-trees when regenerating adjacent chunks.
This mod is not perfect, but it is good enough for most use cases.
