Sounds like the bot is having problems downloading the mesh for the zone, you can try to delete the current meshes and then restart it and wait for it to download new ones and see how it goes from there.
I have the same problem as "oggex"! The bot won't fly to the next spot! I've tryed on a clean HB install.
your mesh folder is located in your Appdata if you have Win7. C:\User\Your Window User Name\Appdata\Local\HonorbuddyMeshes
