Somewhere around the dense cloud reconstruction step, the path to the photos gets mixed up within the project.
When the photos were loaded into the project, they were navigated to via a soft link. I suspect this problem is due to a mistake in treating soft links in the linux version of the software, but it only became a problem later after resaving the project.
Question: If the paths to all the photos in the project have been corrupted in this way (4000 photos for this project), is there any way to relink them? I really don't want to spend several days rebuilding the dense point cloud.
