I have noticed a few threads of toons running into walls etc trying to get somewhere. One thing I have noticed and watch to avoid is to make sure hot spots are not to close to a wall where a resource or something on the otherside your toon will try to get. I also had one hot spot between areas and it kept running off to grab a resource that would pop in every once in a while and the toon got stuck on a tree. I removed a few problem hot spots and cleared up the issues. Hope this helps someone else.
