When using Better Timewarp's slow-mo physics warp, the camera's position freaks out, normally ending underground. Furthermore, it then seems to disregard the position is has been set in, as far as it no longer sticks there. The issue doesn't occur with standard physics warp

Here the position has been set, and all is working fine

The only change here is timewarp
Further testing shows pretty much an entire incompatibility, unfortunately; keyframes get mispositioned, and can't be moved, the dogfight camera's position get's thrown too
