It’s why I wish both Pribyslavitz and Vranik had a smithy hut and remained open at basal operations level (respawned NPCs). Then, the plausibility just changed, and the bands of Cuman and bandits that appear at various places across the map make more sense. They’re away from their base out on a mission
To preserve the narrative of KCD, keep the numbers relatively light after the sacking. And, if one wants to maintain the (false) appearance of more realism, have them be more skittish.
A really simple change can make this already contrived landscape (remember Skalitz was sacked in Mar when foliage is sparse) have more internal consistency
