Here a guide for Trouble in den event. You need to focus on BT Logan route. But tbh, the difference between N and BT is who is the event starter and who will end this event. The most processes are the same.
I tried all the steps, but nothing new happens in the dark swamp and there isnt any new question marks at the specified zones in the misty abyss or the wolves den, and wolves den lvl 2 is locked for me. Though on step 6 , theres a swamp werewolf there that im able to fight, but i tried killing, dominating, and submitting to it but moving to step 7 theres no talk option that appears.
