It’s not bugged, it’s just not very well planned/put together. The first time I played it through, this happened to me as well. Unfortunately I didn’t read Goel’s post, but he figured it out. After the big fight you have to stay on the road. You’ll fight a few spectral things and eventually come upon a camp filled with ghost NPCs that aren’t mentioned at all. Dude will say something, then you continue to follow the road until you get to the temple and it will then work.
