IndexError: no such group

Dear experts,

I got the error "IndexError: no such group" [1] at the very end stage of
the gridpacks production. You can find the corresponding logs and the output gridpacks in https://cernbox.cern.ch/index.php/s/ULEK1OT4hQmrtMJ

The used cards and the documentation are placed in the following
repository: https://github.com/fmanteca/aTGC_UL_samples

Given that the W boson decay is defined in the madspin file and the NLO
reweighting is applied over the proc_card processes, a change in the the
order of the reweighting and the decay steps through a patch is
needed as discussed in
https://answers.launchpad.net/mg5amcnlo/+question/482763 . Maybe
this fact is related to the error.

Any help is welcome.

Thanks,

Pedro
