I don't understand why you're posting, as a bug, what you got wrong as a command.

I'm pretty sure I remember even going to try and help you with it and seeing you sacrifice the statue while I was trying to share the correct command.

That you didn't get the syntax of the command yet does not make this a bug. That you did it for a lantern instead isn't a bug, etc.

In Carrion Fields there are quests that you can *FAIL* and then not complete. So don't be caught off guard if you do XYZ thing that makes you unable to complete a quest. Instead just go find one of the MANY other ones and kick its butt.
