Thank you for your response. I updated to 2.1.2 but have another problem now. After completing the quest for collecting the souls for the Arena, I received the message for the Underground quest. Well, I completed that quest, and after returning to Kvatch with the Soulstone, I saw the arena rebuilt and thought: OK. Then I waited 8 days in Cheydinhal and, after returning to Kvatch, I found the Arena reverted to a not-rebuilt state. I tried to type "setstage KRArena 10" to start the quest but the arena is not rebuilt. There is a way, at this point, to force the completion of the Arena and start the quest? EDIT: Nevermind. Eventually the messenger reached me and started the Arena Quest.
