I am unable to carry a normal tent (civilian tent) on my back.
I can only carry it in my hand.
Second thing. When I have a backpack on my back and the tent in my hand, when I then try to switch the two.. (it gives a blue box around the tent (signal of swapping something (as far as I know))) it bugs my character.
The tent drops on the ground and I cannot use my hands for anything until I re-log.
