Elevator Backpack Loss

So I don’t know if this glitch has been reported. Being a busy man while building my base I tend to afk a lot while waiting for stuff to grind. I have an elevator that is bottomless because well, I’m not done yet lol. Anyhow about 4 times now mainly because I’m not paying attention, I die in the elevator. After respawn no backpack. Logically it should fall and be in the dirt below but it seems to be falling through the world. Thoughts?
