As far as i know you can only change the firemode on the M4 and AUG and at least yesterday i was able to change the firing mode on the AUG to single-shot. However, switching of the firing mode is bugged and as you said, there is no indicator, so vote up.

I'm pretty sure, that there is a hack that let's you teleport to a player who's logging in.
My experience: I logged in (in a bush) and was killed after 5 seconds by a single AKM shot. A friend of mine logged in on a rock above me to defend my gear but got killed in the same manner.

Sorry for pushing, but this issue is very enoying! The game crashes in 3 of 4 cases when i leave the server.

Sorry for bad quality.

Maybe tomorow. Until then i have a picture:

This is the rock i am talking about. She got stuck on top of it, launched in the air and landed between the bush (left) and the tree (right). The funny thing is: where i'm standing (in the background) is where i saw her corpse and where she is standing is where she is seeing here corpse.
Here is my view, don't know if this matters...

Happens to me sometimes, not that often. I don't know about a problem between waterbottles and canteens. But i noticed, that sometimes this problem is temporary and sometimes i can't 'drink all' until i log out. My thought was, that this happens on laggy servers.

I'm going along with some low-value loot. Military zombies could have some bullets, civilian zombies stuff like screwdrivers.
Please no guns. There are way to many gun spawns at the moment.
