When I open the game, then go to Options >> Control, then set the "Special Mission Button" to any button like "ALT", and click save... everything will be OK, but when I sign out from the server and log in to it again I can see that the button that I set for the "Special Mission" has been cleared and I must set it again, I think it's a bug, so please can you fix it :) ... you can see the photo to understand what I mean.
