I am at the tonal lock in Arkngthamz, which I initially got wrong when I first entered. The tones did not play when I shot at the locks, and now they will not reset. I have read that this is a known bug, and many people have suggested waiting certain amounts of time, going in and out of the ruins etc. I was wondering, how long is it usually until locations reset? I have gone off to do other quests whilst hoping the ruins will reset soon, but every time I come back its still full of dead enemies and a stuck lock (except, the first time I pressed the wrong button and looted Katrin's entire body - and when I came back, she was fully equiped again. Rest of the place has not reset, though). By now it must have been way over 3 weeks in game time. This also means that wherever I go, a spectral Katrin is still following me around. Which is kinda cool, now I have her plus my dwarven sphere AND Teldryn Sero, but if I have any other mission where I have to take someone into my party, its becoming quite a crowd...

If time is not the issue, does anyone else know of anything else I could do to help trigger a reset? Reloading is not an option - before setting foot in Arkngthamz was quite some time ago and I dont have any saves from that time any more.

Try to go something far away, and wait 31 days (in-game). Then, come back ant try it again. !!!
