Bare-naked Knapford

So yeah, I spend almost the whole day fixing the issue with Knapford, and it's there. But it's really naked. Meaning? Well, the brick structure is not there and it's half invisible.

According to the folder, it was missing this texture "knapfordstationdetailscompletemap.jpg"

Can someone help me out on this? This is from the recent Knapford from SI3D's route released a while ago.
