Backpack Loot Gone/Disappeared

I logged onto BL3 tonight after about a week and discovered my main, FL4K, didn’t have any backpack items, all gone. I checked my alt, Amara, and her’s are all there. The vault is fine. My FL4K is level 53 and have no idea what could have happened to the items but would like to know if there’s any way to get them back.

For the record, I only play solo, no coop, no matchmaking (not for lack of trying to do the Takedown though).

I did do a logoff of Xbox Live, logged back on and tried again with the same results. Right now there are 0 of 40 items in my FL4K backpack. My Xbox gamertag is Force58, in case you need it.

Please advise if there is any other info you need or if there is anything you can do to assist.
