That's a bug? I thought that was incentive to get your adventure level up, and put life into the map. (Although it shouldn't be flooding your map...)
My biggest thing with the Quests is that they're kind of weak. Their should be rare lvl 1, 2, 3, 4, ect. Quests that offer more than potions and consumables.. Picking up a staff, sword or spear that's not magical is kind of shallow. Anyway if quests where awesome im sure we would love to see quest locations before we can venture into them.. That we we could block them from other factions or adventurers taking the location before you.
