Upstream has released updates that appears to apply and compile correctly.
This update has not been tested by PaperMC and as with ANY update, please do your own testing
My recent work on serialization is now in CraftBukkit so was able to drop the patch and Paper
is now consistent with upstream.

Subject: [PATCH] Fix issues with entity loss due to unloaded chunks
|
|
|
|
Vanilla has risk of losing entities by causing them to be
|
|
removed from all chunks if they try to move into an unloaded chunk.
|
|
|
|
This pretty much means high chance this entity will be lost in this
|
|
scenario.
|
|
|
|
There is another case that adding an entity to the world can fail if
|
|
the chunk isn't loaded.
|
|
|
|
Lots of the server is designed around addEntity never expecting to fail
|
|
for these reasons, nor is it really logical.
|
|
|
|
This change ensures the chunks are always loaded when entities are
|
|
added to the world, or a valid entity moves between chunks.
