Some blocks have changed their place each time I resume my game

Hello,

in order to give a sharpen description of the issue, here is a list of what has been happening for a while :

• each time I resume my game many blocks of many types are not at the place they were when I left the game ;
• the blocks I notice are : dirt blocks, stone blocks, wood fences, wood doors ;
• I could verify that Endermen are not the cause ;

Is there anything I can do ?

 

Thanks guys, your job is great. The game keeps beeing awesome !

 

Regards,

Julien
