I am legit stuck and idk what to do
I was looking for Harvey and I decided to run around. I somehow ran between the desk and the chair and I can't get out.
I'm guessing you right clicked that stool which sat you in it, and then "dismounted" to the left of it instead of the right. If it happens again, you could try hopping back onto it, then hopping off it to the right (by keeping your cursor to the right).
