@BIS, It's a not big bug, but it's very annoying to the player during combat. For this reason, the player character can be killed, because this bug prevents to control the player's character effectively.
If the player is in a prone position, and change your weapon from the primary to the launcher, then the player's character automatically rises to the full height and begins the animation of taking the launcher from his back.
At this moment, the player wants to save the life of his character and presses the button, which corresponds to the //**Crouch body position**//.
User can press the Crouch-button even 10 times, but it will not work, until the the switching animation is not be finished! The duration of the animation of switch to the launcher approximately 3-4 seconds. All this time the player's character will not be able to sit down and will be the perfect target for enemy. And ONLY, after switching animation, the player character will respond to the **//Crouch command//**, and will be crouched.
**Note!** For comparison, if the player will change his weapon at the full erect position, then this bug does not occur! **The problem will occur only if the player has started the change of weapon from a prone position.**
@BIS, Please fix this!
