Same issue here but with a BPactor with InstancedStaticMesh
LogNavigationDirtyArea: Warning: Skipping dirty area creation because of empty bounds (object: InstancedStaticMeshComponent /Game/_Maps/TestMap.TestMap:PersistentLevel.BP_Manager_2.InstancedStaticMesh)
Can’t package because I also have a crash related to this BluePrint,
if I found something I tell you here
