So I have been storing my items in Breezehome, having just bought Vindral Hall I decided to move my more unique loot out of Whiterun and head to Markath....... but my Chest is empty all of my items Nightengale Set, Dark Brotherhood Armors, Guard Armors, Deadric Items.......... everything is gone.... is this a glitch or something or did I get robbed??

Heard you can get robbed but didn't think they'd take that much stuff.
I did have an issue with Breezehome where I would store 1000s of arrows, all my steel ones disappeared.
I was reading in another blog that anything you REALLY want you need to keep on yourself which makes me think it's a glitch.

Holy crap, that's not good. I've got loads if stuff held there. Is it just in Whiterun the problem occurs?

Not sure what happened. i have had all my stuff in Whiterun home since the beginning with no issues. At one point i did buy the house in Markarth and started transfering my stuff. Decided against it and moved the stuff back but throughout the whole ordeal nothing ever disappearded. Do you possibly have an earlier save when everything was still there ?

I keep all my stuff in WhiteRun House as I heard my Solitude house was bugged and I neve had any issues on the 360 so far.

i just leave Lydia at home in whiterun.

i have never been robbed.

try that once you reload the save that has all your stuff.

Just out of curiosity, how long were you away? I've gone out intending to stay out for days and ended up coming back to dump loot in Riften. Before that, same kind of thing when I was using the three barrels at the Blacksmith in Whiterun for all my storage (instead of buying a house) and never lost anything - that I noticed, anyway.
