Just spent 1 hour enabling and disabling mods. I determined that when I have this mod (v 0.1c) enabled there are places in the world that become impassible. The example I went through is Fanueil Hall the scaffolding beside the building. Cannot move through it at all, or use the ramps to loot the super mutants or boxes. Disable the mod (0.1c) it is accessible, I then, re-enable it and I and my companion are both blocked again from the same area. I ran into this in a few other areas but thought they were a glitch and was easy to get around. This location you cannot access the scaffolding from either side. I decided to do enable SS2 again and play through since the latest updates. I don't remember this being an issue with the previous version (0.1a) of this mod, that was a little while back now. I am on PC and have all the DLCs with the latest SS2. (SS2 is still enabled at this point.)
