As if anyone somehow wouldn't know that by now, but since you want to know all the bugs and I didn't see that in the acknowledged bugs part: Rapidly placing single wall sections screws with their placement. Placing one section and then placing another will make the second section start in the middle of the previous one. The upshot is retarded looking mess of concrete that fails to provide adequate protection and is nearly half od the intented lenght. "Then dont do it and place walls in giant sections" is not a valid argument. Shit's still bugged for one, two is that doing that will net you a bullet between the eyes before you can place that. tl;dr: Fuck this place ment.
