@PranQster, just by way of empathy, we're also having a problem getting AI to use a elevator, under 2.07. This was a new, very tall elevator with just 2 stops. Worked fine for the player. The AI never used it, even in a map that had ONLY the elevator, and its two landings. Still, you might try creating a similar map to shed light on your hypothesis that it's the alternative path that's interfering in your case.
