Was carrying cooking pot with 4 random items in it and when i dropped it to get inside it the pot stayed suspended in the air and did not show on the HUD nearby items. It was visible to the player eyes but otherwise was gone. The 2nd pot I found and set down just completely disappeared. I use pots regularly and this has never happened to me before.
I have noticed in 0.59 several other items suspended in the air but visible only. They do not show up in the HUD nearby items. Some of them were immediately adjacent to other items that would interact with the player normally.
