I have noticed that, at least in multiplayer, some people have a nasty habit of undoing your hard-made barricades. I know for a fact that, in build 31, TIS made it so that a player may only interact with curtains from the inside. I feel that the game would become much more fair and immersive if looters were made unable to interact with barricades unless they accessed them from the side they were barricaded from. P.s. I am tired and writing on a phone, plz no judge :[
