Last everything again

So was farming for a band of cytarac (cant spell) when for whatever reason the save failed and I lost my moze. I was mad, but I said screw it, just restart a moze an relax. When I started up the moze, I was going to make the process easier and sell some old junk. When I got to sanctuary I noticed my lost loot was empty…then I checked me bank. So again lost all my items, and apparently the upgrades for it because I have to re buy them. Back up your saves kids

Also, lost my Halloween stuff to, like my skins and stuff. Like what is that even tied to for me to lose it and moze together?
