My suggestion is that the Exit Zones (the part of the map where the ground is shaded brown, and if you walk over it you go the world map) be changed in some places.
First off, I get problems with Junktown sometimes. Sometimes when I try to leave, the exit zone is visible, but sometimes when I try to leave, the exit zone is not visible.
Second, I get problems with not being able to get the the exit zone at Reno Stables (I think that's what they are called, the stables north of Reno).
I don't know how hard it would be, but I suggest that at least one row of tiles be added at the bottom of these maps to make it so that people can leave easier.
Does anyone else get this problem?
