I'm not entirely sure yet how git lfs + attributes work but I think it replaced binary crlf with lf It broke my Terrain.asset file, which seems to be in binary

Not sure how noone mentioned here yet, this is made to look like an official thing with the "gitattributes" group and all but this is just misleading.
