Folia/patches/server/0012-Skip-worldstate-access-when-waking-players-up-during.patch
Spottedleaf 388cdacd1b Initial pass of 1.21
Most significant changes are to portal/teleport logic, there may
be some bugs there. Not really concerned about the passenger
teleport, as Folia had already added support for that.

Not sure how the spark changes are going to work.

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.
