Unfortunately, due to glitches and bugs with Minecraft 1.8, we can no longer allow players to use a Pickaxe of Containment, Broken Spawners and Reinforced Spawners. This is due to players illegitimately changing their properties.
Spawners have been blocked from placement. Please modreq any players suspected to have these spawners IMMEDIATELY. Any spawners found will be removed (this includes rooms containing spawners where players have placed them previously).
We have to remove custom spawner rooms due to new players not having access to have their own following this amnesty, which makes gameplay fair for everyone.
If you'd like to spawn mobs, you are welcome to use a "Dark Room", but please remember that mobs should have full access to hit you, and should not be restricted in ANY way.
