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..)

The herblore bug is caused by the combat timer, and affects any continued herblore controller (crushing, making pots, not just unicornhorn) probably intended to prevent auto herbloring while youre in combat
I cant seem to replicate the torch bug but i recall i had it too

I will deploy a possible fix. I cannot verify that it's completely fixed, because I'm unable to reproduce the problem reliably.
