Main Weapon is Gone

I'm playing some Breach bosses with a friend and when I come back to my hideout from my portal in the Xetsh boss fight I get a message saying that "trading has been disabled in this hideout" even though I'm in my own hideout. My friend that is in my party shows he's not in the same hideout as me but its my hideout we both entered from my portal. So I teleport to him using the blue dot on his name to get back together. A few minutes pass and I notice that 1250 dps quarterstaff is completely gone from my inventory and is not in either weapon slot 1 or 2. Its completely gone. I checked my shop and all my selling merchants to see if I sold it but nothing was there. I checked all my stash tabs and its nowhere. Its completely gone and now I have no quarterstaff that costed me a ton of divine. Im dead in the water and have no more div to get another one. How to I get my staff back?
