There is a problem with the tent, and the fact that you can't use any of your items when you are in it. If the tent gets down into a hole that is too small, and you fall down, you will not be able to dig yourself out! You can't even commit suicide with grenades.

The dev might already be aware of it, but in any case be careful when digging your tent a hole :P (or if an enemy digs a hole under it)
