Yes, for 2.10, the continue marks a little different. Whenever you use a Entance/Exit warp or a Scrolling Warp, the screen that you warp to will be your save point. If that Dmap has the continue checked you will start there forever until you hit another Entance/Exit or Scrolling Warp. If not it will only happen if you die and start there.
So with 2.10 use Entance/Exit and Scrolling Warps to be the save points. If you don't want a save point there use instant-Blackout or other tricks to make the warps look normal.
