probably "ammunition arrival time" was at [OTHER XVM SETTING] / XVM Sight / Aim Info / Sight : Arrival Time
It worked in last version. But it doesn't work now (v.1.16.1.0_09)
I check it's missed while playing arty. but I did not checked it with non-arty.
But I checked it's missed at setup file.
I want to restore this option.
