[NOTE: Similar to issue #0010162 that has video]
Couldn't stop the player from running (couldn't rotate view sideways either) in the middle of a weapon swap while doing so until it threw me off a 3 stories high tower to my death.
It would help if the player could remain in control of his movements while doing any item/weapon spwap or prevent him from going somewhere he would not want while doing so (force stop player from moving).
I was on top of a prison tower with a raw loaded 1911 Pistol in from-the-hip raised aim mode and was switching to my raw loaded Mosin 9130 (From keyboard [1] to [2]) while running (not sure if I was sprinting) to be ready for long range (I also had a pistol holster). Immediately while doing so and turning around to face to another direction, my player stopped rotating (for most raised mode swaps, the players usually stops translating but can still rotate) and kept running straight forward and prevented me from stopping of moving backward for 1-2seconds until I found myself splattered on the floor, dead, 3 floors down.
