So a creeper blasted my chests and all of my items are on the ground and unfortunately, I did not have wood to make new chests so I left them on them on the ground to get wood. 34 jungle woods collected later, all of my items are gone. Including my armor and diamond sword. Do items disappear when they're not in a chest or my inventory?
Items despawn after 6000 game ticks (5 minutes) of being in a loaded chunk. Source
Meaning if it took you more than 5 minutes to collect the wood, the dropped items are gone forever.
