I just killed the first baddies that had throwing axes. After looting a bunch of new weapon types, I equipped 1 axe in each hand, but the hero sword did not go to my satchel inventory. I cannot find it anywhere except on the blacksmith during the crafting menu, it is floating infront of the mini hero. When I switch to hero and grab the sword it works like normal but of course I cannot place it in neither left nor right sheath, nor my satchel. I was able to upgrade it a few times because i had the mats but when I go to play the normal progression mode as my hero, the sword is still missing from my satchel and my player.
