Description

Nav mesh is still affected by a nav modifier volume when added to a sublevel and then the sub level is removed.

Topdown character will not move into the space affected by Nav Modifier volume so not a rendering issue

Steps to Reproduce
  1. Open Topdown project and hit P to see nav mesh
  2. Create a new sub-level and add a Nav Modifier Volume to the sublevel so that it affects the navigation
  3. Remove the sublevel
  4. Build Navigation

Result: Nav mesh is still affected by the Nav Modifier Volume

Expected: Nav mesh reverts to its original state
