Detour crowd cause character stuck on landscape

My character cannot move normally on the complex landscape when the AI controller is inherited from DetourCrowdAIController

here is a video to show the issue: Crowd AI lagging on lanscape - YouTube

if inherited from AIController, then everything ok.
if inherited from DetourCrowdAIController, then stuck in some point of landscape.
Any suggestion to fix this issue?

Hi WFredC,
I have the same problem here, did you find any solution since?

No… have no idea to fix that, I just make the landscape more smooth to avoid the bug happen.
