You can respawn in Hardcore + use cheats in a hardcore world Using Open To LAN

when you go to open the world to Lan, I would believe that the cheats option should be inaccessible in hardcore mode, YES, I do know someone would want to be able to use /kick but in hardcore there is not supposed to be cheating

 

 

 

That is all, Sorry for being a bum and reporting this game changing bug
