I got 2 caravans on their trade route trying to get through a small gap at the same time, so nothing can move through the passage. Here is a screen shot.

Here is a save file
I am experiencing the odd crash also, mainly when exiting the game or changing interfaces, This only seemed to start happening after loading a previous 1.00 save with the 1,01 build. So this may not be happening if I start the Campaign again, I don't know. Will try tomorrow. In any case I thought you would like to know about it.
Aside from those couple of little things, I am really enjoying this game. Great job!, to all those involved.
