Folia/patches/server/0013-Skip-worldstate-access-when-waking-players-up-during.patch
Spottedleaf 4a59238743 Update to 1.20.2
Very early build, network configuration switching is supported
but not tested (note: changes need to be backported to Paper)

Changes:
 - Supports per player mob caps
 - Adds entity tracker optimisations which are not in Paper
   (and will not be ported to Paper due to plugin conflicts)
 - No longer reverts paper distance map optimisations, as
   those are replaced by the NearbyPlayers class

These changes should bring Folia in-line with Paper's optimisations
at least (probably more given the entity tracker optimisations),
still missing features like world loading / some commands

Subject: [PATCH] Skip worldstate access when waking players up during data
deserialization
In general, worldstate read/write is unacceptable during
data deserialization and is racey even in Vanilla. But in Folia,
some accesses may throw and as such we need to fix this directly.
