I am a plain blunt man, with a plain blunt problem...looking for a simple solution. ..

.
.
I found myself in ToB, and I had stored all my Watcher's Keep stuff in my d'arnise stronghold...including my wardstones etc and the poison head of the Flail of Ages...now I can't make the flail, and can't finish Watcher's.
I have few computer skills...can anyone come up with a "For Dummies"-level solution to this problem that doesn't involve me having to replay the whole if ToB?
