Title: Mob Spawners not working..

Version: 1_0_4

OS: Windows XP 5.1 32-bit SP3

Java Version: Java SE 7 Update 25

Description of Problem:

The monster spawners in Hexxit are only appearing as cages with nothing spawning, I've found a couple castle dungeons, a volcano dungeon + a dozen ships with none of them spawning their mobs. I've watched livestreams like CaptainSparklez and he got me interested in trying this but why aren't the mobs working for me?

Are you, by any chance, flying past them in creative?

[MrsMarik]

Does creative mode change that? The most recent pirate ship I dont think I was in creative mode, it was huge with TnT cannons near a village but nothing spawned.

Are you by any chance playing in peaceful?

[MrsMarik]

No im on normal, I never switch to peaceful.

[Valkon]

To my knowledge, certain mob spawners won't do anything unless you're near them in survival mode and at a difficulty they would spawn in.

Okay ill spawn a new singleplayer w/o cheats and try to find them and see if that works. Normally I keep cheats on just in case I need a command block lol
