@sawenzel This check will most likely break all ongoing productions (from @mpuccio investigation), it is still the right thing to do...

Hi @jgrosseo ,

Do you mean that from the moment when it is merged, all jobs will fail, not passing the test?

This concerns only MC. Probably not all but quite some will fail. At least Max found this in a number of AODs. I do not have answers to your other questions in the ticket...

Hello everyone, after discussing with @sawenzel we came to the conclusion that these cases might be due to pruned particles in the kinematics. We will have a look in details to check that this is the case and that no physics is harmed (there is already quite some certainty about this, as the keepPhysics function in Stack keeps primaries and their offsprings).
The current solution will make the AO2D conforming to the data model and will not disrupt current productions.
