Does it work to do it as a team? I read it as having to repair them all yourself, but that seems to be impossible. With 8 barricades and 4 or more logs per barricade, you just can't pick up the logs fast enough to have time to repair the barricades. Especially since you would have to make a second trip to the log piles to get enough logs.
I don't know why the log pick-up has been made so slow.
