        Git Large File Storage (git-lfs) has not been set up correctly.
        Most common reasons:
        	- git-lfs was not installed before cloning this repository
        	- this repository was not cloned from the primary gitlab mirror.
        	- The github mirror does not support lfs.
        See the book at https://book.veloren.net/ for details.
