Visibility issue with smoothlos in fast forward observer mode

[Langbart]

to reproduce

• Default settings applied
• Create a replay in which your unit establishes an outpost in the outskirts of your area.
• View the replay, but at a minimum of 5x or even better 10x speed and set the view to that player.
  • Alternatively, you can start a game with delenda_est activated and set the game speed to 10x.
• the visibility does not adjust (20x) or lags behind noticeable (5x), if you lower the speed below 2x it does work properly.
• See GIF/image below for more clarity.

reproducible

When watching in 20xfast-forward with smootlos=true in A25b, the visibility works correctly.
