This is caused due to the DimensionManager in CB worlds not being registered by NMS, we fix this by copying CBs behavior of using the world providers DimensionManager, vs using the actual dimension manager of the world

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.
