So by now many of us have experienced it- logging in today to find out we have to re-do the past several day's worth of work.

I have the following two questions about how the game saves information in the hopes it will offer some safety:
1. Does saved data for things in my vault work on the same system as saved data for my character inventory?

2. Does saved data for what I have put up in the Auction House work on the same system that saves data for my character inventory?
