Decoupler model switcheroo

[The Ideal Gas Lawyer]

I wanted to make a stronger and heavier version of the hydraulic detachment manafold to help tame the XL SRBs on my updated Jool V rocket and I'm having some problems. I copied the folder for the detachment manafold from the .../gamedata/squad/parts/utilities/ folder to the .../gamedata/Jool V/ folder I made and made a few small edits to the config file and a whole bunch of things changed. Aside from things like the name and the description, I simply changed rescaleFactor from 1 to 1.25, ejectionForce from 450 to 650 and mass from 0.4 to 0.65. Simple right? Well thats where everything went horribly wrong. the Detachment manifold model was suddenly replaced by the TT-38K model and things started falling off and exploding on the launch pad. I changed the rescale back to one and that fixed the spontaneous disassembly on physics load but the model still changed to the 38K.

?????????? What the heck is going on?

Here's the full contents of the config file, the only other things in that folder are copies of the .mu/.mbm files from the original.

If you have n parts in the same folder, KSP is seriously confused and mix everything, even if many different models are specified for each part !

You have to use MODEL { } thing to make it works (be carefull, remove the .mu file extension in it)

ex:

MODEL

{

model = Squad/Parts/Utility/radialDecoupler/model

}

//mesh = model.mu

So problems crop up when you have multiple parts with the same model? I'm brand new to this whole modding thing so bear with me
