the info screen showing how to use the map some times freezes leaving the overlay and I cant move.
(I really love the premeis of this game and am exited to keep playing but, glitch.)
it works does the time between hordes go up because i cant really go past the nearby town.
The zombie sheriff appears randomly in 8 different spots around the farm. Look for a zombie with an arrow pointing down at it. If you do a lap around the town you should be able to spot him. Entering and exiting a dungeon will reswpawn and reset the zombie sheriff again.
Hope this helps,
