Ring at start of game not properly restricting movement.

So I think like 3-4 weeks ago I noticed that if I moved quickly enough I could move slightly past the ring that prevents you from leaving shop at the start of the game. I thought it be fixed in short order. It wasn't and I've finally decided to actually report it. Since occasionally (and I do mean occasionally, at random) this DOES allow me a very slight head start when the ring disappears. Hasn't effected any of my games so far but it still bothers me as a very obvious bug
