Last patch had some mayor unforseen consquences in which civil war broke out more often than not. Very sorry about this! This patch should fix that!
Best wishes and lots of love! <3

For more details: I previously found that when attacking merchants they carried on as usual, ignoring that their friend just died. So I wanted to change that. So I made sure they all turned hostile and set their task to "attackPlayer". However, I set this reponse for ALL humans when attacked by whatever. Meaning a rat bit your settler or a merchants arriving.... well 'Woops', to say the least.
