I'm doing the early level Blades stuff for Caius - run around Balmora and try to get info, basically - and after bringing back a Dwemer Puzzle Box for the guy in the Fighter's Guild basemant, he mentions that if I come back later he'll be able to give me a key that apparently goes to some place in that particular ruin.

When I come back a day or so later, he has no key. Do I simply need to wait longer, or until I get to a particular level, or is this just an unfinished/bugged side quest?


Edit: nvm, I found a reference to this in the FAQ. I'm running a non-goty, unpatched, un-Tribunal/Bloodmoon version, so it's probably a bug, but nothing to worry about.

Not much to worry about. The doors to the lower levels aren't that difficult to pick, and there are scrolls abundantly found in random loot to do the job.
