That picture is mine, but problem is the same. I have seen some bandits using this to kill people. By my way I just max out graphics then I have fps drop and finally get lagging, starting running by the wall. Thats all.

Same problem here. You can walk through the walls in every building. Just need to get fps drop, but I think where is many ways to do it. Today some bandits killed me because of this bug. Please fix this bug.
