Navmesh of previous scene is not disappeared

[dlghwls]

Hello, this is bug about navmesh baking…

1. Bake navmesh in ‘Test’ scene.
   
   
   
   
   
2. Bake navmesh in ‘Test1’ scene.
   
   
   
   
   
3. Run ‘Test1’.
   
   
   
   
   
4. Move to ‘Test’.
   
   
   
   
   
   As I know, when I move to other scene, the previous navmesh is disappear.
   But, why is this? If I repeat running and backing, even though the scene folder is empty, navmesh is remained.
   
   
   
   And this problem affects in build file not only editor.
   
   
   Please is there anybody who know about this? No matter how much I searched, I couldn’t find it.
   
   
   Thank you.
