Spottedleaf 7bc26ecc74 Update Paper
Additionally, fix ActivationRange using global state to store
the AABBs it checks entities against. This fixes an issue where
entities would not be activated when they should be.

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.
