When I open the Market stand, it comes up but then you can't see anything. So you can't even see X to close it. I end reloading the game completely since there is no other way to get out of it. It shows you standing next to it and the close up so you know that you are in that section but it's like looking through smoke because you can see the farm through it. I have had it occur with other projects as well. It happens at least several times per week.
