Most quests are still not working, because of the new NPC-chat system.
Quests only involve certain NPC's, that are assigned in the quest.
The new system does not recognise the NPC's with a lastname yet,
but the developers are working as hard on it as possible to fix it.
Can tell you, that there are 5 NPC's ingame that are a smith.
And most likely only 1 of them is assigned to be used in the quest.
So for now everyone has to wait for the devs to launch the fix, when it's ready.
Btw you posted this topic in the wrong section, although it's an older topic, that is revived again.
It's not ment to be posted in "Technical Help: Problems BEFORE entering the game", but should have been posted in "Technical Help: IN GAME bugs (after loading world)", because it is a bug ingame.
This is related to the NPC chat problem that wasn't entirely taken care of yet. Thus NPCs who have two names (first and a last) may not accept items from players at this time. Hang in there for a fix.
