Comrade’s Hammer revolver has disappeared?!?

Sup chooms! So hey, I had the Comrade’s Hammer revolver on one character/playthrough and fuckin loved it. Then I picked it up with a different character/playthrough but it didn’t show up in my inventory. THEN, it wasn’t in the inventory of the first one either! It just disappeared… wtf mate?! Anyone else encounter this kind of bug? 👾
