Subject: [PATCH] Paper PR: Prevent zombie reinforcements loading chunks

|
|
When a zombie calls reinforcements it tries to spawn them in a random location within a 40 block radius of the zombie,
|
|
before spawning, it checks isSpawnPositionOk() for the position which loads the block to check if a mob can spawn on said block.
|
|
This patch ensures the chunk at the random location is loaded before trying to spawn the reinforcement zombie in it.
