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] Do not read tile entities in chunks that are positioned
|
|
outside of the chunk
|
|
|
|
The tile entities are not accessible and so should not be loaded.
|
|
This can happen as a result of users moving regionfiles around,
|
|
which would cause a crash on Folia but would appear to function
|
|
fine on Paper.
