Can't select files if a torrent has already started

[legacychimera247]

Well if i start a torrent and want to select or unselect some files after, i cannot do that cause it's simply not working

If i deselect a file will continue downloading the same and the same for the contrary, and this bug is present since forever unfortunately

I guess it does not matter if a file is just a partial download or some pieces depend from the next file in line (or previous) cause other clients are perfectly able to do that

Hope it will be solved anyway :)
