I don't have all the time in the world to play and let's admit it... the levels can sometimes be huge. So i pushed through to get to the next area and the IRL clock was ticking. I had to quit playing. When reachin the new area i unlocked that teleport thingy on the ground (blue circle) and left the game. Next time when i logged in, that progress wasn't saved and i now have to go through the whole damn thing again.

So why can't all of these simply be a permanent checkpoint/teleport? During act one, safe places seems to have been marked with a tent icon. In act two there nothing of the kind. But this doesn't really help because i need to be able to log out after each area... not every third.
