Workaround for Slime Spawning Bug in Minecraft 14w21b

Minecraft 14w21b, the newest snapshot most server administrators trust to not ruin all the worlds, has one annoying bug: Slimes don't spawn. This is actually a really huge problem if you need sticky pistons, which are necessary for automation. Fortunately, using /summon to create Slimes still works.

So, you can use this fact to create an administrative contraption to simulate normal Slime spawning. Do something akin to this:

• As a server operator, switch into Creative mode
• Find an unobtrusive spot in a spawn chunk for a small box
• Create a multiplicative hopper-dropper clock
• Configure it to pulse every two hours (or whatever you'd like)
• Hook it up to a command block with the following command:
• /execute @e[type=Creeper] ~ ~ ~ /summon Slime ~ ~ ~

This command will spawn one Slime at each Creeper. You could change the type, but I recommend Creepers because they are only found in the Overworld and are not spawned from any spawners. So, with this device set up and operating in a spawn chunk on your server, you'll be able to hunt Slimes in a fashion similar to the non-bugged behavior.
