Subject: [PATCH] Optimize Persistent Data Loading
|
|
|
|
removes Mineshaft loading legacy as we had pre 1.13.2 to avoid managing
|
|
that very large data file from legacy systems.
|
|
|
|
Previous to 1.13.2 these data files were never loaded to begin with, so they
|
|
effectively do not contain valid/relevant data.
|
|
|
|
These files take a long time to convert on large worlds and crashes the server.
|
|
|
|
Additionally, cache the result of a file being missing so we don't keep spam checking it.
