Ok, so the devil tanto I have to steal for the thieves in Ald'ruhn is not where it should be - I looted the place ages ago and it wasn't in the chest then (I went back to an earlier save before I looted it to check if it was so I would know if I sold it or not and it wasn't there). I then loaded that save again and tried going to the thieves before looting the place and it was there that time. The thing is, I've done loads since I looted the place so I don't want to have to do all of that again. Does anyone know how I can spawn the devil tanto into the game so I can continue my thieves quests as this is obviously a little bug I've come across where it just hasn't appeared when it should?
Many thanks
Edit: Ok I managed to figure out how to work the construction set lol and I've managed to get it now. In case anyone else has the same problem, the code to type in the console is:
player->AddItem "devil_tanto_tgamg" 1
