There's a very strange issue. I've configured enemy behaviors with random movement. Some to follow the player, others to move away. Some even to ignore the player and move randomly.
The problem is that if the player doesn't move, the enemies don't either; they only walk when I do. I've attached a screenshot of the configuration (the graphical interface is in Spanish, but I think you're familiar enough with it to see each field right away).
I also posted a short video showing the problem.
