Subject: [PATCH] Entity load/save limit per chunk
|
|
|
|
Adds a config option to limit the number of entities saved and loaded
|
|
to a chunk. The default values of -1 disable the limit. Although
|
|
defaults are only included for certain entites, this allows setting
|
|
limits for any entity type.
