Bug Description

Hi expert,
I'm generating a process -
generate p p > W+ W+ j j j j
add process p p > W- W- j j j j

decay W+ > l+ vl
decay W- > l- vl~

and i am getting error
Command "generate_events run_01" interrupted with error:
KeyError : 'W+'

I haven't tested with p p > w+ w+ j j j j as it takes too long but instead did

generate p p > W+ j j
add process p p > W- j j

decay W+ > j j
decay W- > j j

I get the same error

But it worked for me if you make the W into small letters w+ w- instead of W+ W- in madspin decay
I think it's because madgraph organizes the particles with the lower case letters in the middle and madspin doesn't do that, there is small confusion.
