Subject: [PATCH] Only count Natural Spawned mobs towards natural spawn mob
|
|
limit
|
|
|
|
This resolves the super common complaint about mobs not spawning.
|
|
|
|
This was ultimately a flaw in the vanilla count algorithim that allows
|
|
spawners and other misc mobs to count against the mob limit, which are
|
|
not bounded, and can prevent the entire world from spawning new.
|
|
|
|
I believe Bukkits changes around persistence may of actually made it
|
|
worse than vanilla.
|
|
|
|
This should fully solve all of the issues around it so that only natural
|
|
influences natural spawns.
