I've been save scumming every turn and still can't hit 50% of the time with any of my mercs (not just the sniper). Meanwhile redshirt soldiers are getting headshots with shotguns and pistols from several tiles away.

Sometimes after you get out of the ring Darren wont pay you if you are turned away from him. and you cant control where your soldier will be facing after you exit the ring.

Also sometimes I noticed that you cant take money from your bank account. Buttons are just grayed out. To fix that problem just exit the game and start it again.
