Subject: [PATCH] Prevent Waterflow BlockFromToEvent from loading chunks
|
|
|
|
Many protection plugins would unintentionally trigger chunk loads
|
|
by calling .getToBlock() on an unloaded chunk, killing performance.
|
|
|
|
Simply skip the event call. as CraftBukkit blocks changing the block
|
|
of unloaded chunks anyways.
|
|
|
|
This keeps behavior consistent, vs inconsistent flowing based on plugin triggered loads.
