I was smelting a sea pickle for a lime dye to apply the bed.  After I pulled it out of a furnace.  I went to my bed to break it.  The game crashes immediately by one hit.  After I reloaded the world: 2 villagers disappeared, split screen player's perspective was altered into several blocks above from player position then back to normal in a second, and continued crashing every time I touch bed.   Luckily, I have the practice of saving and copying world in between.  I loaded world from the last save.  Everything's back to normal.  Will not smelt sea pickle again until farther notice.  World was created in bedrock.
