The last issue for me is, that people I rescued from bandits sometimes getting cloned. This result in bandit encounters with bystanders in which the same person is a captured victim and a bandit at the same time. On the next day the same person can get captured multiple times by the town guards, resulting in a slave market full of clones, if you grind e.g. Wimborn Outskirts on a day. The console screenshot shows scripts errors, that happened by grinding bandits, but they don't necessarily show any script errors for the cloning issue.

This two erros seem to cause the cloning of people.
I restartet the game, loaded a save, go to Winborn Outskirts and rescure one victim without any error thrown.
On the next encounter, this both errors get thrown. Then I win the battle and both bandits, and the one victim are all clones of the same person I rescued in the encounter before.
