NPC Dissapear after about 500m

Hello, I buld a 4kmx4km map in Unreal Engine 5.4.4 und use an Metahuman NPC with convai 3.6.9. When I ask to follow me, we walk together for a while. Abter aprox. 300-500m he suddenly dissapers. When I go back to the Point where we started. He is there and I can ask him again to follow me with the same result. How can I avoid this. I am using world partition and NavMeshBoundsVolume to define where the NPC can move… Thanks!

Could you please check where the NPC is in the scene view?

its located somwhere on my map (see screenshot above)

Sorry I found the issue, when you place something in World partition it is connected with the loading grid even if the object follows you and if it leaves the grid it is unloaded. So I had do uncheck the metahuman spatially loaded. Has nothing to do with the convai plugin.

Thank you for sharing the solution.
