Paper/patches/server/0718-Use-getChunkIfLoadedImmediately-in-places.patch
Shane Freeder aa52bf9e33
Remove "Implement-Chunk-Priority-Urgency-System-for-Chunks" (Fixes #5980)
Mojang made some changes to priorities in 1.17 and it seems that these changes
conflict with the changes made in this patch, which in some cases appears to
cause excessive rescheduling of tasks.

This, however, is not confirmed as such but seems to be the behavior that we're
seeing to cause this issue, if mojang has adopted the changes we suggested,
then a good chunk of this patch may be unneeded, but, this needs a much better
look than I'm currently able to do

Subject: [PATCH] Use getChunkIfLoadedImmediately in places
This prevents us from hitting chunk loads for chunks at or less-than
ticket level 33 (yes getChunkIfLoaded will actually perform a chunk
load in that case).
