Checking kills tab in achievement panel will also cause this error.

I see. I killed one bio operator in the past: "mon_zombie_bio_op": 1 But I can't see it in the kills tab. When I remove this record from the JSON, the error is gone in diary.

Perhaps ID of that monster has changed EDIT: it seems bio operator has been removed from the game completely. But the update didn't take into account the existing record in kills? But I still don't get the relation to zombie child. And the error is still present while killing a zombie child.

Killing monsters with death_guilt seems to be causing it. And, if you delete all the strings in your save (not only in kill_tracker, but also in character_butchered_corpse, mon_zombie_medical_regenerating, character_ranged_attacks_monster), the error is gone.

I confirm that fixes the issue, however it seems weird to me that this hasn't been removed by the update. Anyway, thanks!

osuphobia found the culprit, workaround was to remove all references of removed object from the save.

Reopening, this is a valid bug that we want to track.
