When saving a replay, your replay might have a slowdown of -nan(ind)

Screenshot of the replay GUI showing the slowdown.
Figure 1: The slowdown shows -nan(ind).


This bug can be done if the player saves a replay right after starting a run.


This is because the replay internally does not have a slowdown value. As such, the game defaults to the value of -nan(ind) for slowdown.
