I'm trying to trick the player into thinking that failure isn't always "failure" and success isn't always "success," so reloading the save is pointless because the quality of the end result is not guaranteed by the quality of the roll.
They'd know based on the outcome, unless you hid the fact that a roll was taking place at all. I'm all for hiding rolls from the player as much as possible, especially when you're able to in a computer game, but the build up to and release of a skill check is part of the fun for a lot of people.
