Still not fixed in newest pre-released. 12w25a

Slimes still despawning in swamp biomes.

To add to what Fienxjox said, I also set a customized world to swampland only, created a bunch of command blocks to kill all mobs except slimes, and then ensured it was a full moon. Still most slimes flash in and out, with very few slimes actually remaining spawned. Needs fixing.
