I fixed my disappearing husband glitch!  Maybe it'll work for you. ;D

Okay, so my husband disappeared on me and I couldn't find him anywhere, even the bread crumbs couldn't find him.

So this is what I did:

I installed Fable 2 to my hard drive on my xbox 360, you can find out how to do that here: YA - Installing xbox games to hard drive

Then after that was done,I got back into the game and he was still gone

But then I went on a quest that lead me into a dungeon.  The light wellspring or something like that.  It's around the light temple somewhere. (Sorry I can't give more information on that, but I'm sure most of you know where it is) The quest was to save The Temple of Light. Which leads you down into the dungeon to kill some guy.

Anyway, so after that quest I had to go back to Bowerstone Market. (where we live) and there he was in the town center! My husband is back! He had like 3 gifts to give me too since I hadn't seen him for awhile. Lol.

But anyway, if any of you are having this problem then this might be a way to fix it, even if you don't have the quest, you could still try going into the dungeon.
