A little bit of context:
The process I am trying to simulate is single production of vector-like quarks and their subsequent decay via w/z/h boson. I am trying to use it witin ATLAS EDM and the athena cache that has a stable support for the reweighting module uses MG version 2.6.1. So far I have been using MG to produce the vlq and decay it to the boson and quark, as in the following process -
add process p p > j VLQ bb / tp tp~ p t t~ y y~ bp bp~ x x~ z h a, (VLQ > ww bb)
Reweighting has worked just fine for this process. With this job option, decays of z and t are taken care of by Pythia. Everything works just fine for this.
Now, the problem:
Instead of specifying the production of vlq in the process, I now only specify the final state I want and constrain the process using coupling orders, as in the following commands-
add process p p > j w+ b~ b / p t t~ tp tp~ bp bp~ x x~ z h a YWB^2==4
add process p p > j w- b b~ / p t t~ tp tp~ bp bp~ x x~ z h a YWB^2==4
Allowing such processes are interesting for a number of studies, including interference. The coupling orders should make sure that I have two vertices with Y in association with W and b, essentially regenerating the same set of Feynman diagrams as before. However, with this command, reweighting fails with the following set of errors-

The reweight card is as follows-
change mode LO
launch --rwgt_name=M10K05BR040303
set KY 0.5
set MY 1000
set WY auto
launch --rwgt_name=M10K15BR040303
set KY 1.5
set MY 1000
set WY auto
launch --rwgt_name=M11K05BR040303
set KY 0.5
set MY 1100
set WY auto
launch --rwgt_name=M11K15BR040303
set KY 1.5
set MY 1100
set WY auto
It is the exact same reweight card that does work for the first process I mentioned.
From the log file, I get the following error:
