Well, the server's running 1.8 now (per /icanhasbukkit, CraftBukkit version git-Spigot-8a983f9-e81edfc (MC: 1. (Implementing API version 1.8-R0.1-SNAPSHOT) to be precise). While that does mean we get a few good things, it's also had a few issues.
Water and lava blocks are gone, completely. 1.8 no longer has them.
Similarly, /c pokechu22 gives nothing, as the slabs have lost their inventory representations.
It's nothing too important though. It's probably possible to make a plugin that used numeric data values to create fake water blocks, though.
