Error while compiling: Quests.cs(422,31): error CS1061: Type `ItemCraftTask' does not contain a definition for `owner' and no extension method `owner' of type `ItemCraftTask' could be found. Are you missing an assembly reference?

Same error needs to be updated for the new wipe

Search for OnItemCraftFinished and replace it like this:

        void OnItemCraftFinished(ItemCraftTask task, Item item, ItemCrafter itemCrafter)
        {
            var player = itemCrafter.owner;
            if (player != null)
                if (hasQuests(player.userID) && isQuestItem(player.userID, item.info.shortname, QuestType.Craft))
                    ProcessProgress(player, QuestType.Craft, item.info.shortname, item.amount);
        }
