When you're using a scope with an adjustable zeroing the default is 500 meters.
Whenever you switch to your alternative sights and back to your scope the zeroing resets back to 500 even if you had it set for example to 300 meters.
I would like the zeroing to remain at the adjustment that it has been set to previously. I use my alternative sights frequently and when it resets back to 500, i'll be shooting over my targets and its not convenient to reach over to the page up page down keys while in combat.
This is more of a bug report as there is NO REASON FOR THE ZEROING TO CHANGE BY ITSELF. It should stay the same unless you change it yourself.
