Ehhhh, I personally don't really get that mechanic in the game. Also, adding that feature onto the rest option would likely make escaping from the mental ward impossible.

Oh that's what I was thinking before. Sleeping I can understand not resetting the restraint, because it's progress and all. But the mental ward where you get the shower where the gear is taken off and put back on... That doesn't make sense that it isn't reset.... Might need to make the "rest" option in the cell restore energy to keep at it, before shower time.
