Thanks very much!
Yeah, the barricades are pretty unfortunate as they are now; they were part of the original idea, which was moreso about picking and choosing what lanes are open in order to get the materials you need, while minimizing threat. It ended up straying away from that and the barricades just don't really fit in with how it currently works.
And that does sound like a bug to me. Added to the list for whenever we have the time.
