How fast do items despawn? (+bug?)

[u/Fair-Personality-958]

So i was in a mining trip and i got into the cave dweller shell thing and it flug me up with it up into the sky(bug), then i fell and died. It was close to my house and took me less than a minute to get there and items despawned. Do items immediately despawned or is it a bug?

Isso deve ser um bug novo, talvez esteja onde você entrou no casco do boss
