OK, this is getting ridiculous.
Last week several quests in Dwarven Valley were broken like "Strung up", "Lawful Salvage", or "Plugging Holes". Also, the PvP encounter was permenatly "on" but unplayable. After the server reset it seemed to correct itself. However there are people reporting the problems are back and quests in Icewind Pass are broken as well. For example, I can't harvest the Remorhaz legs after acquiring the Ice Blade. Something is seriously borked in Icewind Dale repeatable quests and needs to be looked at soon.
