Night Fatigue

[ComradeP]

As far as I know, there are no separate checks for different forms of activity during night turn. Your units either accumulate night fatigue, or they don't.

Night fatigue gain is at most half a unit would normally recover. This is where it gets a bit foggy.

Fatigue recovery is normally between 0 and twice the Fatigue Recovery value in the parameter data dialog. At night, it is doubled. Night Fatigue gain should be between 0 and twice the rest value, because the fatigue gain is up to half of what a unit might normally recover.

In reality, it isn't as units can gain more than 20 fatigue if they move at night with Fatigue Recovery set to 10. That might be due to rounding of some sort.
