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.
. Scope maintains the vision mode regardless of weapon fire mode
- 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.
