So last night I visited my bank to find that my upgraded space was gone along with all the items I had in it. I had 74 items and 80 bank slots. Upon returning to my bank, I found it was empty and there were only 60 bank slots. I tried relogging, and I got 54 of my items back, but still only 60 slots. The problem still existed this morning when I logged in. Has this happened to anyone else?
