I found a bug in getObs() that returns invalid results on maps that are much taller then they are wide, and the x/y checked for is beyond the width.

I made a fix in my working copy, and made a test case to check for it (wee!)

From what I've found the bug is in g_map.cpp:line 431 int MAP::obstruct(int x, int y)

The line that says
if (x<0 || y<0 || x>=mapwidth || y>=mapwidth) return 1;
should be
if (x<0 || y<0 || x>=mapwidth || y>=mapheight) return 1;
