I had an option for that in the config a month and a half or so ago, but it never worked consistently so I ended up removing it. As eastwind has discovered, its fragments live on inside mod.js, and it's possible to re-enable with a few changed lines and by adding the relevant config option back in, but.. Yeah. Personally, I wasn't able to get it working consistently.
I remember the option being in the mod about a month or so ago and its a shame you had to take it out. I don't suppose you'll be happy to put it back in IF someone will help you untangle the web for you?
I need more variety in my game it was more fun when the same faction as you didn't try and kill you but I have small hope it will come back HAHA!
