I noticed a while back that my reports show KOs for scenarios though none of the requests in that scenario KO’d.

Looking at the simulation.log, I do see KOs in the wrapping identifiers for the scenario - but, again, no KOs for any of the requests.

Any idea what could be causing this / what I should be looking for?

Not really. Would you mind sharing a simulation.log so that we can try to reproduce it ?
