Yes, thank you. Should be fixed now.
Thanks. I think Vradnir didn't return during your gameplay because this was one of the very few "quests" I did on the game, and back then I was working under the assumption that there wouldn't be any single event that would take more than one day. So, the check for this quest only checks if the exact number of days that have passed are equal to the number of days it takes for Vradnir to return.
That isn't the case anymore, as I eventually learned how to make an "event announcer" appear only when you are able to be there to witness it, but there might still be some "quests" that aren't updated, like the one you mentioned.
I'll have to make a specific fix for that because the way this event is structured right now.
I have been working on it since the end of last year, and I think within two months is a realistic goal, since most of the content is done and its a matter of fixing bugs for the most part.
