I was running g g > h h with a SILH NLO model I generate with feynrules when I encountered this problem.
Command "generate g g > h h [noborn=QCD]" interrupted with error:
KeyError : 'MB'
Please report this bug on https://bugs.launchpad.net/mg5amcnlo
More information is found in 'MG5_debug'.
Please attach this file to your report.
And this is content of debug file:
