what would you have lost from storage?

I actually checked my bank, when I saw the advisory, before the server went down. I lost nothing (had 20m and an 8 slot bag in there). The roll back will cause me to loose 8 books I bought from somewhere in the FM. I am hoping I can long on and rebuy them before the shops move, since most of them were AFK character shops.

The servers were taken down. That means no shop remains where it was. You need to hope the same person you bought from will put them up for sale again.
