Can't change parameters : Music / Money droping / Leveling + Crashclient error

[VegaFontana]

Hello, I have a litle problem with your pluggin,
I can't change the parameter I want to :

Here is my module.yml :

Modules:
store: true
leveling: false
banking: true
mailing: true
regions: false
texturepack: false
custom mobs: true
battle music: true
death chest: true
npcs: true

But even with this I can't find :

How can I change the music of the batle.

How can I change how many money the monsters drops

And the more Important, Even if I have disabled the leveling :
I use MCMMO for this.
My players still have a "Lv : 3" instead of the McMMO lv next to their names.
And worse, the MCMMO GUI has disapear =/

Ps : What is the "custom mobs" module, I have seen no .yml file to parameter this one ?

Note : The pluggin works perfectly, but when i place a safe, a shop or even a tulip, the client crash, I reload and the item is placed, that's not a big issue but that's a bit anoying to reload the game everytime.
The server say : read timeout / disconect.endofstream

I am using :
The last Dev builds of Spoutpluggin and spoutcraft
On Craftbukkit 2.0 with :
Vault for CB 2.0
McMMO for CB 2.0
RpgEssentials_1.2.10

Hope you'll see my post.
Have a nice day ;)

I get out the Vault Pluggin and now the second issue is fixed, I can place what I want whithout crash.

Moreover, I can see the McMMO Gui now, (but still got the level name problem)

Edit: The crash problem came back after two minutes of playing the game. I can't place anything anymore without crash now. Everyime I reload the server, i can place things without problem during a small amount of time but then, it crash again when I place things.

Edit2 : Now restarting server don't affect the bug, event if I reload before I connect, It crash when i lace something... =/

I think it were a Ram problem but I put it to 4GB without shaders and It still crash the client when I place something.

Okey So I have solved a Half of my problem the two last hours :
That was because of incompatibility of other pluggins, I just keep these ones :
Dimension door
McMMO for CB 2.0
RpgEssentials_1.2.10

Now I see the good level name on the name and the Mcmmo GUI, just have the problem of money droping from mobs and music battle, and also the client crash.

The crashing is caused when you place a custom block on a new chunk.
If that chunk already has a custom block on it, the client will not crash.
But when you try to place a custom block on a chunk that has no custom blocks on it, it will crash.

Okey I've just tested it, That's true !
That's why there is no crash on the generated word with the pugin, the ores underground.

Thanks angelofdev

Two issues left ;)
