Hi-I think there might be a bug in the Tomb of Urd quest-right after the first full moon, I got the option to explore the tomb the first day but I picked "Talk to Larik" first and the quest disappeared and hasn't come back (I think I passed 1-2 days).

Not a bug, every time you talk with a character there's a timer that reset. The option to explore the tomb will reappear for sure in the next few game days. I made this to avoid plot conflicts (talking, exploring, doing 500 things the same day lol).
