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.
