[MC-32136] LAN worlds never save any changes

LAN worlds never save any changes. Steps how to reproduce:
1. Create a new world (any gamemode)
2. Open to LAN
3. Change anything (destroy blocks, change gamemode ...)
4. Restart world
5. All changes are resetted, the game didn't save any changes

MC-32067 Some blocks after you break them and save the game a bit later, it pops up again in the same place when you open up the world again
