Rebuilt nav mesh with streaming level

Hello mates,
Currently, my project encounter a small problem, which is the nav mesh inside my streaming level. Everything work fine, my character can use the nav to move, when I add stuff(mesh, rebuilt blueprint,…) my level automatically rebuild nav mesh, which is a normal thing in unreal to me. The thing that bug me is that if I use nav mesh inside a streaming level, after rebuilt, nav mesh only calculate thing inside my persistance level and won’t calculate the object with collider inside my streaming level, in order to have a correct nav mesh, I have to manually hide and then show all of my streaming level for it to rebuilt correctly. Now this won’t be a big problem as long as I remember to do hide/ show streaming level before each built, but I must say it would be really nice if unreal folk can do some magic to let us skip this.
