Subject: [PATCH] Handle bad chunks more gracefully
|
|
|
|
Prior to this change the server would crash when attempting to load a
|
|
chunk from a region with bad data.
|
|
|
|
After this change the server will defer back to vanilla behavior. At
|
|
this time, that means attempting to generate a chunk in its place
|
|
(and occasionally just not generating anything and leaving small
|
|
holes in the world (This statement might not be accurate as of 1.13.x)).
|
|
|
|
Should Mojang choose to alter this behavior in the future, this change
|
|
will simply defer to whatever that new behavior is.
