I can confirm this. Here is a link to a picture of the bug:

EDIT: And... There is that bug where team mates can't wear clothing out of crates and we have to 'dress up' dead bodies and loot the clothing off of them. Hence the chat...

I don't really see the controls being hard at all. 90% of the time, all you need are these:

WASD - Movement
G - Throw grenade
R - Reload
Mouse wheel and button - Scroll through action menu and select action
X/Z - Crouch/prone
Left/right click - Fire/Aim Down Sight
Q/E - Lean left/right
I - Inventory
N - Night Vision
Alt - Free look (Turning your character's head while not turning the body, useful in vehicles)

For the stance modifier, it's just Left CTRL + WASD.

It's almost the same as usual FPS games but with a couple of more keys. Almost all of the keys above are reach-able by your left hand.

Yup, me and a friend tested the wounding/armor in multiplayer yesterday. He shot my legs, didn't break or anything... Kept shooting it until I died and respawned.

Also happens when you switch from driver to another seat. Which is really strange.

It seems that bullets go through the wooden frame but not the glass.
