Bukkit

What steps will reproduce the problem?
-I've installed the plugin and a mate told me it works well... but I can't see myself turned into a creeper (or other creature). Every OP of my server is having the same problem.

What is the expected output? What do you see instead?
-Expected: the plugin should morph each player into a creature.
-What happens: the player can't see himself morphed, but other ones see the player morphed.

What version of the product are you using?
-MobDisguise v1.7

Do you have an error log of what happened?
-The logs show nothing, the console doesn't either.

Please provide any additional information below.
-Server version: Bukkit 1.2.5-R1.0 (Build #02149)
-Minecraft client: Spout 1.2.5. Also tried with Minecraft 1.2.5.
-I'm not using any kind of permission plugins (just default OP ones).
-Creatures tested: Creeper, Sheep, Zombie, Chicken, Enderdragon.
-Also tried client & server 1.2.4 versions. Same problem.
-Other plugins used: AuthMe, dynmap, Dynmap-Factions, Factions, Lockette, NoEntityGrief, WorldBorder, WorldEdit.

I don't think that's a bug; just a lacking feature for the spout client. (Assuming this is possible at all.)
