This patch does not appear to be doing anything useful, and may hide errors. Currently, the save logic does not run through this path either so it did not do anything. Additionally, properly implement support for handling RegionFileSizeException in Moonrise.

Subject: [PATCH] Fix NPE on null loc for EntityTeleportEvent
|
|
|
|
EntityTeleportEvent#setTo is marked as nullable and so is the
|
|
getTo method. This fixes the handling of a null "to" location
|
|
by treating it the same as the event being cancelled. This is
|
|
already existing behavior for the EntityPortalEvent (which
|
|
extends EntityTeleportEvent).
