It's a vague sounding issue, though I had the exact one. Can you please submit proof onto this thread so that the staff can evaluate the problem and help you from there? Thank you
If you placed it it’s unlikely you’ll suddenly get given an unplaced one back. That’s happened to many people who never got refunded.
It would help more if your friend made the thread. But also you don’t place things because of lag. You place things by knowingly clicking a block on a surface. Without some proof of what you were actually doing with the head for it to get placed and how lag made that happen you likely won’t get a replacement.
It can happen, especially if you're rubber banding a bit. I've had times where I go to right click an item frame, but as I click I rubber band back a block or two, and right click on my pillar instead. Still very uncommon, though, and still the player's fault.
