Additionally you do not become winded while sprinting with hands up so you can pull out a rifle and scope without wobble.

Just happened to me. Second floor of pub in Berezino.

Edit to add: Found my corpse outside on the ground. Apparently glitched through wall and fell to death.

Confirmed. Although I was originally trying to go up the broken stairs and a zombie rammed me through the wall into the trap room.

Another player happened by and desync was enough to let me run partly through a wall so he could punch me to death. During the attempted death the server restarted and I found myself in the hallway and able to proceed normally.

Confirmed. Came to add this, found it here.

Yeah, what is the point of item quality if it all functions perfectly while ruined? The ONLY items I've noticed a quality difference on are optics and even then the long range scope has no quality differences.

Might try unparking CPU cores. I got a 15 FPS boost when I did. Windows 7/8 has power saver software that disables cores unless they are specifically requested by an application. Check this link:

When is this supposed to be fixed? Because it definitely is not fixed now.

Confirmed. Tried two lanterns in different conditions (One pristine and one damaged). Tested outside and inside. Tested on ground and in hand. In all cases the glass lights up but casts no light on anything.

Confirmed, uploaded a couple screenshots. No mods taken a few seconds before full mods while 3rd person freelooking and walking up a hill.
