I have the harbour elevator gate key, and I opened the door.
However I still can't walk through, there is an invisible wall there.
[6.55] Harbour Elevator Gate invisible wall
I can confirm this bug My best guess is that the door's collision box is not properly removed when you open it.
I could work around the bug by accessing the harbour via another route. Worth of note is that I could walk through the door afterwards, my best guess again is that since my detour loaded different maps into memory, the door's collision was correctly removed when I came back to the harbour.
