Bukkit

Version 1.32

    * Minor changes to config file creation
    * Added in a special block config option for redstone. (Redstone controlled fuids now need to have the special block powered for flow to stop)

Apparent Liquid height is based on what is next to the liquid.

IE. A fully surrounded water block at height 1 will look like a height 1 water block. A height 1 water block surrounded by air will look like a height 4 or 5. Its just the way minecraft renders liquids that are not attached to anything. Nothing can be done about it server side.

Setting the height of a fluid to something other then 0 will cause that liquid the be unable to be picked up with a bucket.

IE. if you dump a bucket of lava at a fluid height of 1 then that lava will remain at a height of 1 and you can not pick it back up with a bucket. Its just the way minecraft works.
