I've been doing The Dark Brotherhood Forever, constantly, for one week and then out of nowhere, I didn't reacquire the quest once I killed my last contact -- I don't remember which contact. I tried to do a console command to reacquire the quest, but I kept getting two messages: 1. "Get can not be found"; 2. "0" .
I was wondering how do I reacquire a radiant quest that doesn't place itself into the quest log?
