UE4 Failed import for PathFollowingComponent

After rebasing my AIControllers to DetourCrowdAIController, on loading the project I get the error:

UE4 Failed import for PathFollowingComponent

The controllers do not path around each other as they should as well, but it works basically even with the error.

bump, any one else rebased npc’s from AIController to DetourCrowdAIController and experience this?
