Killed my character that I had gotten to healthy status and COMPLETELY geared. Really annoying. Should be a high priority bug.
Edit. I think having a gun draw may be what causes the issue.

Stacking storage is possible for nearly any item that allows storage. Assault vests cannot be stacked more then storing the items inside the vest then storing the vest inside a pack. The vest is a 3x2 inside a pack. Cargo pants and other pants that store 2x3 can be stacked unlimited, but take some effort to do so. You must first equip a pair to store a pair inside via double-click and having the pants be the first open 2x2 spot. Then this process can be repeated until the server crashes I guess. This is extreme op to store ammo because reloading is not affected by stacking. Also hotkey items seem to be unaffected by stacking and can also be still be accessed.

Happened to me as well, just as it happened to chronerion. Switched servers and the light on the lamp is there, but the environment remains unlit.
