Updated with more detail.
Can't replicate with buttons or Redstone wire.
I don't think this is MCPE-22063 as the door is shut and the pressure plate is deactivated but the texture hasn't updated.
Seems to work correctly in Windows 10 Edition.
I Really Think I Has Something To Do With The Saturation's Regeneration properties.
About 200 When I Tried
Found A Better Method
You Will Need:
A Peace of armor with a increased health attribute
A Pool Of Lava
You Will Also need the saturation effect
Step one: Put on the armor
Step two: Walk Into The Lava
Step three: Take Off The Armor
The Death Menu Should Appear
You Will Now Be In A Glitched Health State
Re-Logging Will Fix This
1.9 also has this glitch
The Seed Is 1280411122 And The Coordinates are -180 70 610
Note: This Doesn't Happen In Superflat
I Also Found That Ice Has This Problem
Here's The Crash Report
I Already Know That This Is A Duplicate
It Happens In The Default Texture Pack And Most Other Texture Pack Including Faithful 32x32
Ok
Here's an improved video of the issue running on the Windows 10 Edition: https://youtu.be/B4tlq0Xkua4
