Error while compiling Quests: 'ItemCraftTask' does not contain a definition for 'owner' and no accessible extension method 'owner' accepting a first argument of type 'ItemCraftTask' could be found (are you missing a using directive or an assembly reference?) | Line: 410, Pos: 31

i get this on load, therefore the plugin doesn't load and quits.

anyone know how to fix this?

Lines 408 to 414 should look like this if you read the other help posts in this thread you would have found this answer. It's only a few posts down.

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);
}

Merged post

but when you fix that issue with that fix you get 2 other issues do just go to the https://umod.org/community/quests/54327-fixed-version-from-calbalt-studios post and download the working plugin I can't say if everything is working in the plugin being it's 9 mos old but I didn't get any load errors in the cmd window.
