On my 2nd day playing this game, I was wandering with a crate just found and, then as I let go of the crate to collect some honey slimes, the crate was standing still in mid air. I didn't know how to Report a bug in game by the time, but it's a good thing that I took a screenshot with steam.
[Link to screenshot @ imgur]I'll be trying to get that bug happen again, but I have to make a new game and wander back to Moss Blanket. Right now on my first world I don't think I have any crates left to find... ^_^'
