AI moving in Viewport mode but not in standalone game. I think Navmesh volume isn't loading in standalone - any fix for this ?

No im not level streaming. Can you tell me how to make the maps visible ? And what do you mean with save them can you tell me how i can do that ? I hope there is some simple solution how to make it or maybe at least some tutorial you can point me to.

I just found this node


Is this what i would need for the map save?
