Not to be discouraging, but I couldn't get them to work properly with AI in my last 2 FMs and just decided to monsterclip them off. There were a lot of other problems than just AI not following paths (e.g. falling into the shaft and dying, getting slammed by opening/closing doors and dying, etc).
So if you have a complicated setup it might take a lot of work to get it bug-free.
If that's a test map you have there, it might be worth raising a bug report and attaching it. One of my main pet peeves with TDM is bugs that limit design choices. IMO these should be high priority for fixing over all these graphics features that keep getting introduced.
