I teleported to barbarian village and the torches flickers, teleport away and teleport back resolve the issue, another way is to type ::reloadmap command. My settings are all tick marks except ground decoration and the first roof option (left side).

After killing unicorns, and taking unicorn horns, when inventory has 2 or more unicorn horns, using pestle and mortar on them only change 1 to unicorn horn dust, the other doesnt become, the automatic system issue I think. More specific is done just after combat with unicorn (10 second timeframe combat before logout etc..)
