Hi,

This is a problem I've been investigating recently, and it looks like it is 
triggered when a non-existing AIModel is being loaded *before* 
tile-scheduling is completed. I don't know if/how/when this error occurs if 
you only run the AI system without the trafficmanager. I'm not (yet) familiar 
enough with the tile scheduling code to know what types of error may actually 
trigger this error message.

In the mean time, you might want to check in your preferences.xml file, if the 
AI system has actually anything to do, and if all the required files are 
installed on your system. Below is my configuration:

  <traffic-manager>
     <enabled type="bool">true</enabled>
  </traffic-manager>

  <ai>
   <enabled type="bool">true</enabled>
   <!-- scenario>nimitz_demo</scenario -->
   <!-- <scenario>aircraft_demo</scenario> -->
  </ai>

As you see, I have the two scenarios commented out, and feed the AI system 
through the traffic manager instead. 

Cheers,
Durk
