This warp /warp chill puts you in a little bedrock room with lava under you but glass above that. I always use it for trades since it's sorta unknown and small. But when I was trading with MrParkourGuy, I was gonna meet him there and I had some iron/grass/gold. The payment was grass and gold, but I wanted to give him some iron as a little tip (I do that sometimes) And the floor glitched and I burned in the lava and lost all my stuff! My suggestion is that you add another layer of glass so this doesn't happen to other people ;(
