SmartLinks are removed during Dynamic navmesh regeneration
In 4.11 Preview, if the navmesh is set to Dynamic generation, any runtime regeneration of the navmesh will cause SmartLinks to be removed from the navigation data of that region. The PointLinks will remain, however.
This issue manifests differently in 4.10. When the navmesh is regenerated, the SmartLink remains visible in the pathfinding data and it remains active if the PointLink is present. If the NavLinkProxy has no PointLink, then the SmartLink will not be used in pathfinding after dynamic regeneration.
Thank you for providing your exact steps. I was able to reproduce this issue in a clean project, and have entered a bug report (UE-27377). I will provide updates on this issue as they become available.
Have a great day
