HI, I was building a map wall in the last snapshot (using item frames) with no problem at all then I started up Minecraft again the next day using the latest snapshot ( 19W05a ) and I saw there was no item frames so I thought that Maybe the item frames had just been destroyed. So I went into my files changed put the back up world in the save file and reloaded the game in the previous snapshot. Then I put all the maps in a chest and saved the world. I then loaded the game in the latest snap shot, went to put an item frame on the wall only to find there was on there with a map on it so when fingered it out I destroyed the block and after about a second an item frame fell on the floor.

You can replicate this bug by going on any Minecraft world in the latest snap shot and placing any block and then place and item frame on that block, you won't be able to see it but if you break the block an item frame item will fall down.

Looking at the picture bellow you'll see no item frame but the hole wall has item frames on it.

PLEASE FIX THIS!
