For a long time (as long as I've been base building) barbed wire has continued to remain in place even when the door is open. This results in being cut/close damaged as you pass in and out of the open gate. I just died as a result of closing my gate - the character continued to be slashed repeatedly even though I was far away from the gate. I died within seconds - faster than I could log out to hopefully avoid this fate.
Fortunately I spawned close and most of my inventory was salvageable... gates/basebuilding add an awesome dynamic to the game, but this forces me to not use barbed wire again until it is fixed.
