The bug where omega occassionally draws random characters on the terrain
map is in drawplayer(), which is in oscr.c

This function has a coupls of static variables which keep track of the players
last position. They have a sanity check for normal maps, but not the country
side. This will give random characters if (for example) you restore a game
which was saved in the countryside.

The following patch may help: I would also ask the author to have a look
and see if inbounds may be used in the countryside. This patch is a hack
from someone who is not at sure what he is doing, but thinks it looks
better this way.
