Is this still an issue? Since 1.05 my trade routes have not been attacked once established. And before that, normal stack will do.
Yep, it happened yesterday in my game. I have 3 cities, and naturally all of them linked with Caravans, and both my Caravans got attacked by Creatures, who initially started outside the influence zone, then came on into my zone and attacked it, and naturally won the battle easily, lol.
I know some of you stated to just kill the creatures, well I've done that, the problem is, eventually I'll see respawns just outside my zone of influence, and then eventually they will move towards my caravans. It is interesting how you say if you give them an escort, that they could stick with them after it's done, I'm going to have to try that today.
I will continue to do some more tests to see if maybe it was just some random fluke, or I wasn't really paying attention to my surroundings as much as i should, and will report back naturally.
thanks,
