In Settings->Gameplay, the 'Maximum number of auto-saves slider doesn't behave like the rest of the sliders.

- it doesn't move smoothly like the rest

- you can increase it, but only by cliking in the new position

- you cannot decrease the value(!) even after confirming the warning pop-up

Same bug, every attempt to decrease number of auto-saves causes the pop-up to fire again.  Clicking ok does not change the setting or unlock the slider to be changed as the warning pop up just comes up again...
