Landscapes not working with nav-meshes

Hello , The project I am currently working on uses landscapes as the playable area. This is causing issues with my Ai which functions on other surfaces (bsp’s and static meshes) but won’t recognize move to locations on height-mapped landscapes although move to actor will work and the Ai will chug along this a known issue or am I just missing something, being dumb?

Any help would be appreciated thanks

You should probably post a bug report on answerhub for this. At least you’ll get a response that way. Haven’t confirmed this myself though so can’t answer you.
