Weapon audio can originate from a player's old position after being spectated

[Colin Basnett]

I can't believe we figured this out!

This is actually confirmed to be a Red Orchestra: Ostfront bug as well, and the reproduction steps are the same.

Steps to Reproduce

1. Player 1 spectates Player 2 in "Viewing Players" mode.
2. Player 2 walks away from the position where Player 1 started spectating him from and fires his weapon.

Player 1 will observe Player 2's weapon sound to be originating from the position that he originally started spectating him from. This symptom will persist even when Player 1 spawns into the game. It is only ever alleviated when Player 1 observes Player 2 pick up the affected weapon while in non-spectating mode (in-game) or in "Roaming" spectate mode.

It's also interesting to note that this affects individual weapons, not the player as a whole. This mean that once the player becomes affected after step 2, all of Player 2's weapons will be affected individually and can be fixed individually. For example, if Player 2 drops his primary weapon and picks it up, it will fix his primary weapon for Player 1, but any secondary weapons will still be affected.

I think this might be a native bug being in native final function SetViewTarget(Actor NewViewTarget);
