If you mean the dark forest quest, this quest is just a main story quest. It won't be completed until the end of the werewolf quest. (Which still has not ended yet!)
I see, thank you! But recently I had two doubts, one is that since I defeated the bandit boss, I have never been able to find him or talk to him, so how should I talk to him or did it stop being possible when I defeated him? Another question is about following Seb before the vote, I don't know if I'm delusional, but I think that after listening to his conversation, I somehow managed to reconcile with him, even making him feel relieved. But after I uninstalled it and installed it again, I couldn't do it again, if really reconciling with it is possible, how should I do it?
