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.
