Ok The Bug Really Started Since 1.5 Or Something Similar Especially On Multiplayer Where I And My Friends Play On A Survival World And Sometimes When The Host Enters The World The First Thing He Sees Is The "You Died" Screen When And When He Respawns He Spawns on The World Spawn So He Loses All His Items
The Rest Of Us Have A Similar Problem Is That Sometimes When We Enter The World It Treats Us As We Didn't Enter This World Before So We Lose Our Progress
Additional Info (Might Help You Fix The Bug)
The Multiplayer Problem Is More Likely To Be Associated With The Xbox Live As In My Case We Have A Slow Internet
We Sometimes Play On LAN Network So Keep That In Mind ( This is When The Weird Stuff Happens )
Thanks

We are still looking into the issue with player data changing or being lost at MCPE-55815.
If the issue is still occurring for you in the latest version (currently 1.16.1) please could you add any steps to reproduce the issue at MCPE-55815.
Also, if you have a copy of the world save available, you might like to share a copy of it for investigation.
On Windows 10 you can use the Export world feature.
On Android or iOS you need to use a file explorer to navigate to Device storage > games > com.mojang > minecraftWorlds
On Xbox or Switch the only way is to upload it to a Realm, and then download the world on Windows 10 or Android/iOS. (Please do not purchase a Realms subscription just to provide a world to us - but if you have a Realm already this may be a viable option if you wish to do so.)
If the world is larger than 10MB you can upload the world to OneDrive or a similar file sharing site, and then share the link in a comment at the main bug ticket at MCPE-55815.
Thank you for your help, and for your patience while we look into this bug.
