Bukkit

What is the issue?

Nothing works.

Please provide any additional information below.

/biome set-global -w world Jungle does nothing.
/biome set-selection Jungle does nothing.
I checked with F3, no biome changes.

I am using 0.5

That's... not helpful.

I'm going to need a lot more info than "it doesn't do anything", because it's doing plenty of things here ;)

Does it really "do nothing"? As in, not even an error message comes back? If that's the case, it's usually indicative of the plugin crashing, which is most likely a conflict with other plugins or CB updates.

What CraftBukkit version are you using? v0.5 is built for CB 1.3.1-R1.0, but a quick look at the changes for 1.3.2 doesn't show any obvious plugin breaking changes. (I'll do a thorough test later, and update if necessary.)

Does the server console/log show anything "unusual"? Post any relevant stack traces you find.
