Bug Description
When trying to produce a gridpack for a somewhat complex LO process with complex decay chain, some of the jobs fail with
cluster.f: Error. Invalid combination.
Error: Clustering failed in cluster.f.
Reproducible with below example (picked out one specific process*decay to reproduce faster):
import model sm-no_b_mass
define p = p b b~
define j = j b b~
generate g g > t t~ g g g, (t > w+ b, w+ > u d~), (t~ > w- b~, w- > u~ d)

Hi Josh,
Do you have the banner of that run?
Looks like this depends on the run_card parameter since I do not reproduce this behavior with the default run_card.
Cheers,
Olivier
