The problem is:

         <scalar initialXNum="25"/>
         <plugin type="Polynomial Fit" initialVNum="3" initialXNum="25" initialPNum="1">
             <inputscalar type="Order Scalar" tag="2 (X25)"/>
             <outputvector type="Fit" tag="Fit"/>

In <variables> 25 scalars are created named X0...X25.

In <plugin> it loads (X25) because it could find the existing scalar and _xnum is still 25,
then the output vectors are created with scalars starting at 25 so we have two X25.
When I manually change initialXNum="25" in <plugin> to 26 loading works.

But I'm not sure how to fix this.
I've committed a fix (it increments _xnum before the plugin stores it).

But I hope there is a more generic solution. This bug looks like a principle problem.
