I have finished a quest and I should talk to NPC to take reward but it happens nothing:
I found Orobas dead in his dungeon, but when I talk to Jebediah I can only say goodbye.
in the log the quest is enlighted in green and it says that I have to talk with Jebediah..
it is a bug or i'm missing something?
The same happens with Allan the alchemist and his potion quest
You need not only complete the quest, but have ALL the quest components in your inventory for it to go farther. This happened to me here too. I had the chalice, but not the rare herb -- for one reason or another I had cleared my inventory into the battle tower, so I had to go get it to complete the quest.
