I am aware that there is no TWS sight yet in game, but I have observed the following on the weapon sights that are available as mods, as well as my own.

Steps to reproduce:

• Pick a weapon and mount a scope with special optics, like a TWS
• Switch fire more.

Expected:
. Scope maintains the vision mode regardless of weapon fire mode

Observed:

• Scope switches back to normal view. This happens even on those scopes that do not support normal view, like a TWS sight that only supports thermal optics.
