Same problem, Xbox one, beta. I observed a compound of 32 villagers reach 0 villagers in 3 minecraft nights. I found that reloading the world brought back some villagers into vision. I understand that the villagers are not gone, just not visible or interactive.
There is only one possibility as the steps to reproduce instructs a "double" chest be made. I'm having the same problem, when you open a chest, double or single, the bottom part of the inventory is gone after reloading into a game.
Hey Ronald, tip. Plant birch saplings surrounded by flowers/tall flowers, keep harvesting the trees and replanting the saplings and eventually bee hives will naturally spawn on the the trees.
I've also noted this bug and reported it, I've tested the problem repeatedly and found that some specific items go missing regardless of position in the inventory chest. Specifically diamonds, iron, coal blocks, redstone blocks and nether quartz, sometimes partial items and sometimes an entire inventory of a specific item. I thought I was loosing my mind when restarting a game and thinking that I had at least 2 stacks of iron and was sure I had more diamonds than were in my inventory. I figured I was being somehow trolled by the likes of Donny, 🙂
This has not been resolved. It's Nov 26/20. No change.
