Fix 1.7 streaming sectors crash when moving around a total replacement map (like VC) that presents itself as if in CShadows::CastShadowSectorList but it wasn't that straightforward..

1. 0x6C65746E - "ntel" (corrupted pointer: executing string data)
2. 0x70A6DC` CShadows::CastShadowSectorList`
3. 0x70AD74` CShadows::RenderStoredShadows`
4. 0x7FDC29` __rwD3D9RenderStateTextureFilter`
5. 0x7FE7CB` __rwD3D9RWSetRenderState`
