Error in re-weighting between different groups of operators in EFT model

The key error means that one set of matrix-element does not have a matrix-element for a given initial/final state
in your case this is for
u d~ > mu+ mu- e+ e- s~ c

Now you use an outdated version of the code (2.6.5) if this is a bug on the reweighting side (which might be) then I would advise to check with a more recent version.

Cheers,

Olivier
