While fighting in the nether i stopped to move items into my /bp. When I did so as i closed my /bp I realized my sword was gone. Opened /bp to grab it and it wasnt there. I looked around on the ground and it hadnt been dropped. I am unsure as to where it went as I had literally just been using it seconds prior to it disappearing. I provided a screenshot of the sword I was using as I made sure to take screenshots of all my gear the other day when I started getting decent gear.
