I was given the "find the word wall" quest by Argneir to find the word in Dead Men's Respite, but I already have all three words of Whirlwind Sprint. So when I go to the wall, nothing happens and I'm stuck with the quest. How do I mark it completed?

Did you go back to Argneir to see if he can "finish" it?

When I go back to Argneir he does not give me an option to search for words. The convo is stuff we already talked about.

Anyone?

I cannot think what else to do. I would probably just revert to an earlier save or use the console. I would give you the codes but I cannot find that quest at UESP.

Apologies for not knowing any other solution

I've looked for that quest code too and can't find it. Maybe it's the code for a generic "word wall" quest?
