I was having the same issue, "Missing Required Level of Detail". I was used to upload mesh and even complex riged models into sl, someday, this weird mensage appears on the upload window. After many tests I realize the problem was not on my model but on the name of the folder my model was when i converted it to collada. The folder name had a '#' characther, i changed the folder name and the upload works again pretty good.
