Did you download it by clicking on it and opening it in a browser? or did you right-click and do "save link as"? I just tested it and saving the link works fine from what I can tell.
You can do this but as I said in the Description, I don't recommend you use the parts list from Rebrickable. When I uploaded it the list it created was incomplete, and it messed up a bunch of my colors which I could not fix properly. Highly recommend you use the xml or bsx that comes with the download.
Yes that is correct. They are actually listed as [No color/Any color] if you look in the description. They wouldnt come in as green because those parts dont exist in green in the database. And so I switched them to no color. But see my last post about the parts list on rebrickable...
This was one of the hardest parts for me to find also. Noone seems to have more than 1 or 2 of them at the most. I dont have any suggestions other than to just wait and keep looking or do as Cavegod suggested.
