Not 100% sure what the version number is but i am running Windows 10 Beta Edition.

As most people who play minecraft do, they create a first base to get through the first night, in the base i created on my world on Windows 10 Beta Edition when i intend to leave the game i go back to the base (to be safe), close the door and click "Back to title" then close the game however when i go load up the Windows 10 Beta Edition again and i click back into my world it spawns me outside about 3 - 5 blocks above my base.

What i expected to happen was:
I would spawn back inside my base

What actually happened was:
I was spawned outside & above my base by around 3 - 5 blocks

Steps to reproduce:
