Windows, Version 0.3.0
Had a realm quest to find a map and a treasure (tartarith realm, 84f). I used the map, but the treasure did not spawn anywhere (used the map of farsight to make sure).
Possibly caused by the fact that that particular realm turned pretty small, with just corridors and 1 average sized room in the middle with all the loot there (also had 1 small corridor about 3 tiles wide with nothign much). Had plenty of grey (wall) area to the right, like ~40% of the map size.
