I tried it during the day and night but there's still no animation of the child weirdly walking being triggered, the detective showing up and when I interact with the trees it gives the message "There is nothing here but wild grass". Just to be safe I tried it with my alternate account and it worked so I think the bug/problem is with my main account.
Thank you for your response. Yes, I have already interacted with detective Basile and agreed to assist him. Then I entered Ghoul Swamp and triggered the animation for the child walking weirdly. After following the child and finding the detective at the north east part of the map I entered the maze. The problem is when I used an escape rope to escape from the maze I couldn't trigger the animation for the child walking weirdly nor could I find detective Basile anymore. I tried the same thing I mentioned in my alternate account and it worked but not on my main account so I was thinking it was a possible bug or problem in my main account?
