I am totally stuck on this quest line. Is this quest still bugged? I believe it was bugged in the beta but would have expected to see it fixed. Any ideas if this is still the case?
This bug has now been fixed in the 19 November patch and the dispenser can now be activated.
I think this is still bugged. Best to move on to another quest line. Next patch might fix some of this stuff which should have been fixed for launch. Typical Bethesda 🙁
