The prospecting trainer has started doing what the rosshaven trainers do.
You doubleclick him to learn the daily, choose the daily i.e. daily 10, click on learn quest.
When you doubleclick on him again to hand in the quest the daily 10 isn't there.
You have to go out of arthnell's workshop and reenter to get the quests back on the list and they for fine then.
I reported it when i was doing a lot of crafting in rosshaven but haven't done that for a while so don't know if it is fixed there but anyway it is doing it in EC now
